Indicator Locating Device
|
Keith F. Gallimore |
Fond Du Lac, Fond Du Lac County, WI |
Claim:
The present invention relates to improvements in indicator locating devices for indexing moving fixtures.
In indexing machine tool fixtures, for example rotatable tables, it is important that the fixture be accurately located after each indexing movement. Various means employed heretofore for this purpose~ because of play etc. are inaccurate, and are difficult to readjust if the correct position is lost. The primary objects of the present invention therefore reside in the provision of a novel indicator locating device which is highly ac- curate, which is readily adjustable, and which causes the indicator to register any accidental or undesired displacement of the movable or rotatable fixture so that an accurate readjustment can be made. |

Boring Cutter
|
Erwin J. Kaiser |
Fond Du Lac, Fond Du Lac County, WI |
Claim:
The present invention pertains generally to cutting tools and more particularly to a boring cutter having a cutting tip of cemented carbide or the like. The use of high-speed cutting tips of carbide material frequently presents serious practical difficulties with regard to their mounting. One widely accepted expedient involves brazing the cutting tip to a block or holder of steel. Due to the differential expansion rate between the steel and the material in the tip, there is a tendency for excessive temperature stresses to occur in the tool, thereby limiting its life and also its effectiveness. Another mounting expedient which is particularly well suited for use in large tool sizes involves clamping the cutting tip to the holder by means of mechanical pressure. Arrangements of this type overcome the disadvantages inherent in brazing the tips to their holders but are not always satisfactory in practice due, for example, to the application of high localized clamping stresses which are apt to result in tool breakage. |

Counterbalancing Mechanism for Machine Tools
|
Jesse Daugherty |
Fond Du Lac, Fond Du Lac County, WI |
Claim:
The improved counterbalancing mechanism comprising
the present invention has been designed primarily for use
in connection with machine tools of the type commonly
known as milling machines. The invention, however, is
capable of other uses and the same may, if desired, with
or without modification, be employed in connection with
a . great variety of machine tools having moving parts
thereof which require counterbalancing.
Heretofore planer type milling machines have presented
relatively serious alignment problems occasioned by the
weight of the headstock and its offset or overhanging
relationship with respect to the supporting structure upon
which it is slidably disposed. Briefly, machines of this
type ordinarily include an elongated bed upon which
there is supported a reciprocatory work-supporting table. |

This application is a continuation-in-part of co-pending application, filed 16 February, 1955, now Patent No. 2,787,175.
Claim:
Machine tool work supporting tables must often be made conveniently movable, both rotatable and liftable for rotation, and yet capable of being locked in a precisely predetermined position. A common example of such a workholder is the rotary table or platen used with machine tools such as horizontal boring machines and the like. The performance of machining operations on large, heavy workpieces is complicated by the difficulty involved in orienting such workpieces with respect to the machine tool spindle or cutting head. Such workpieces are generally supported on a table which can be moved to position the work and which can be clamped securely in place to hold the workpiece stationary during the machining operation.

Sliding Way for Machine Tools and Method of Making Same
|
Edwin P. Ormsby |
Larmartine, Fond du Lac County, WI |
Claim:
The present invention relates in general to machine tool ways and more particularly to such ways of the general type provided with bonded nonmetallic wear plates and disclosed in United States Patent No.2,675,276, issued 13 April, 1954, to Jesse Daugherty.
In machine tools of the type having movable members supported and guided in their movements by means of complementary, elongated ways provided on the movable members and their respective supports, it is advantageous to provide relatively soft wear plates attached to one of each pair of complementary ways for sliding engagement with the hard bearing surface on the co-acting way. It has been found that such relatively soft wear plates are most desirably formed of materials having advantages as regards non-scoring and other physical characteristics not possessed by metal plates. Such materials include certain plastics, one widely used material for this purpose being a laminated fabric impregnated with the plastic material known in the trade as "Formica." |

Method for Cutting Metal
|
Walter C. Thuerwachter |
Fond Du Lac, Fond Du Lac County, WI |
This application is a continuation-in-part of my co-pending application files, filed 08 April, 1955, now abandoned.
Claim:
The present invention has as a general object the provision of an improved method of machining using carbide cutting tools having tool angles selected to promote more efficient cutting. This result is obtained in one aspect, by causing a new type of negative rake cutting to take place in metal. It has been standard practice, heretofore, to use cutting tools in both positive and negative rake positions. Furthermore, it is popularly believed and commonly explained, that the contrast between the cutting action produced in these different positions is essentially the difference between "shearing" off material, the action which it is conceived occurs in the positive rake position, as compared with "crushing" or "pushing" the material off, the action which it is generally conceded occurs with the tool in the negative rake position. Thus, in the negative rake position, a much thicker chip may be removed, although considerably greater power is required from the machine itself as well as ability of it to withstand greatly added loads. With carbide cutting materials, the generic name for the various sintered carbide materials which have been developed for cutting tools, it has been found particularly desirable to use negative rake angles. The reason ordinarily given for this is that the carbides while called "miracle" cutting materials for being second only to diamonds in hardness, and temperature and abrasive resistant, suffer somewhat in a comparison with previously known tool materials by reason of being brittle and having low tensile strength. By using a negative rake angle more material may be caused to lie behind the cutting edge, obtaining superior support for the cutting edge by way of a reinforcing of it and as a consequence, the result that the tool bit itself is more resistant to failure by cracking. The negative rake angles which have been recommended for carbide cutting tools heretofore, have been selected to provide this improved support or reinforcing of the cutting edge, but the angles are such that the cutting action of the tool bit may be described as aforesaid, as a "crushing" action, or as a "scraping" or "pushing" action. Such negative rake cutting is accompanied by increased tool loads and as a corollary to that, considerably greater power is required from the machine to produce the high surface speeds used in machining with carbide tools. |

Attachable Ways for Machine Columns
|
Raymond M. Woytych |
Fond Du Lac, Fond Du Lac County, WI |
Claim:
This invention relates to the construction of the vertical ways on the columns of horizontal boring, drilling and milling machines.
In a horizontal boring, drilling and milling machine, the headstock carrying the horizontal tool spindle is vertically reciprocable on the face of the machine tool column. The vertical bearing surfaces on the column are subject to large reaction forces and at the same time must be accurately and precisely maintained. Accordingly, it is the usual practice to mount separable way or guide elements on the face of the machine tool column so that the elements may be more readily machined, finish ground, and treated for hardening of the wear surfaces. |

Operator Elevator for Machine Tools
|
Garner H. Schurger |
Fond Du Lac, Fond Du Lac County, WI |
Original application filed 13 May, 1954, now Patent No. 2,816,485, dated 17 Dec., 1957. Divided and this application 20 Sept., 1957.
Claim:
The primary object of the invention is to provide an "elevator" on which the operator of a large machine tool may ride in ascending and descending the vertical distances he must cover in inspecting the progress of the machine work, making adjustments on cutter tools or tracer mechanisms, and changing cutters or control settings. Transport of the operator is not merely a nice convenience but a real, practical need in very large machine tools, for the fatigue brought about by his climbing, twisting, and crawling over the machine may so diminish the operator's keenness of perception and quickness of action as to bring on a serious mistake resulting in damage to the machine itself or ruination of a workpiece into which much machining time and money has already been invested. |

This application is a division of co-pending application filed 24 Oct., 1957 (and issued on 28 June, 1966 as U.S. Patent 3,258,667), such co-pending application being a continuation-in-part of the now abandoned application filed June 23, 1955.
Abstract:
A phase shift decoder in which digital intelligence in the form of discrete signals or electrical pulses is converted into analog variations in the form of a changeable or variable phase between two recurring waves. The decoder may accept randomly occurring time-space input pulses and create corresponding variations in the phase of the output waves from reference and information scaling channels having the same scaling ratio and normally receiving as inputs the same recurring master signals. The input pulses cause the response of the information channel to the master signals to be selectively increased or de- creased, thereby slightly to advance or retard the phase of the information channel output wave, relative to the output wave of the reference channel. The system disclosed insures that the randomly occurring information pulses are converted into pulses which are noncoincident with the master signals; and it acts to combine the master and information pulses into a stream which contains one more or one less pulse than the master pulses for each information pulse. It is to these latter aspects of what are called the "chronizer" and the "add-delete means" that this divisional application is directed, although the disclosure in the present case is substantially identical to that of the parent application identified below. |

Index Unit
|
Lyell C. Tullis |
Janesville, Rock County, WI |
Abstract:
The index table is carried on a ring gear which is indexed when a rack segment is positioned so an idler pinion on a connecting rod engages the rack and ring gear. On the return stroke and during dwell a cam moves the rack segment to inactive position and a shot-pin gear segment holds the ring. If the ring jams, a spring loaded overload arrangement withdraws the rack segment which will be returned to operation on the next index stroke. The ring gear permits a large center opening and large bearing surfaces. The ratio between the connecting rod shaft and cam shaft speed determines the portion of the cycle for indexing. The stroke of the connecting rod determines the number of indexes. |

Record Reading System for Simultaneous Control of a Plurality of Devices
|
John K. McGee |
Houston, Harris County, TX |
Abstract:
A system for reading an elongated record or tape containing randomly interspersed blocks of two or more types (A or B) of digital data into data processing apparatus so as to continuously control two or more (A and B) utilization devices such as servomechanisms, and wherein different blocks of data are sufficient to keep a utilization device busy for different periods of time. All A data blocks are used in the order of their appearance on the tape without regard to any B data blocks; and all B data blocks are used in their order of appearance on the tape without regard to A data blocks. Apparatus signals when data of either type (A or B) is needed, and means respond thereto for starting the tape reader forwardly. As each block is sensed, means create a signal indicating whether that block contains A or B data. If the block contains the needed type of data, the signals read therefrom are accepted and the tape reader is stopped If the sensed block, or any number of blocks, contains data of the type not needed, means cause the data signals therefrom to be rejected or ignored (the block is skipped) and the reader continues running until a block containing the needed type of data is found, read and accepted. Control means then stop the reader and cause it to run in a reverse direction until the beginning of the first skipped and previously unused block of data is again disposed in the tape reader. Storing and con- trot devices cause any previously accepted block of data to be skipped even though it contains data of the type needed. Other apparatus performs auxiliary functions such as limiting the extent to which the systems will search forwardly on the record. |

Method and Apparatus for Controlling Motions of a Drilling Cutter or the Like
|
Jack A. Wohfeil |
Fond Du Lac, Fond Du Lac County, WI |
Abstract:
In the control of a drilling machine or the like, the drilling cutter is traversed toward a workpiece and its motion converted to a slower feed rate at the instant the cutter engages the workpiece. Such engagement is signaled by producing first and second electrical signals whenever the cutter is moving respectively toward or away from the workpiece, and detecting the momentary appearance of the second signal which results when the cutter strikes and rebounds slightly from the workpiece. |

Daniel J. Steiner |
Kaukanuna, Outagamie County, WI |
Abstract:
In the control of a drilling machine or the like, the drilling cutter is traversed rapidly toward a workpiece and its :motion is converted to a slower feed rate at the instant the cutter engages the workpiece. Such engagement is sensed by producing a signal in the form of a series of pulses having a frequency proportional to the velocity of the cutter during traverse, and by detecting a decrease in the frequency resulting from a reduction in the velocity of the cutter as the latter strikes the workpiece. When such detection occurs, an engagement signal is produced to reduce the velocity of the cutter to a feed rate, and measurement of the displacement of the cutter is begun. |

Numerical Control Systems Employing Conversion of Changing Command Numbers Into Phase Analog Signals
|
Norbert C. Kolell |
Empire, Fond du Lac County, WI |
Abstract:
A numerical control system wherein a phase-variable analog signal is created and utilized by a servo drive to control the displacement and velocity of a movable element in accordance with the extent of change and average rate of change of a periodically updated, digitally signaled command number, as disclosed in co-pending application Ser. No. 555,048; and characterized by an improvement for eliminating "misses" in the phase-variable signal which may result from "leapfrogging" under certain circumstances. A command number in a storage register is periodically updated. It is compared with a reference number signaled by a continuously running counter and which cycles between two values in phase agreement with a reference wave. At the instants during each cycle when the command number and reference number are equal, a compare pulse is created which by its phase, relative to the reference wave, corresponds to the command number. But in those cases where updating of the command number makes it "leapfrog" to a value already traversed by the reference number in a given cycle of the latter, and so that no equal comparison can occur during that cycle, the improved apparatus senses this and generates a substitute pulse closely timed to that which the "missed" pulse would have had, so that the compare pulses plus the substitute pulses form a phase-variable signal without discontinuities and thus provide smoother and more precise operation of the servo drive. |

Machine Tool With Longitudinally Adjustable and Hydraulically Clamped Rotary Machining Spindle
|
Gordon H. Jones |
Van Dyne, Fond Du Lac County, WI |
Abstract:
A machine tool comprising a machining spindle adjustably extensible longitudinally within a rotary support sleeve and releasably clamped to the sleeve by a clamping bushing applied by high pressure hydraulic energizing means positioned on the spindle sleeve in such manner that application of the clamping bushing does not change the load on precision bearing means used to support and precisely locate the sleeve radially and axially and does not apply significant axial stress to the structure that functions to determine the axial position of the spindle to the end that the spindle is clamped for rotation precisely in the exact axial position desired. The clamping bushing has an axial position proximate a precision bearing that locates the sleeve and spindle axially with precision and the high fluid pressure clamp energizing structure that rotates with the sleeve and energizes the clamp hydraulically is situated on the sleeve so that the portion of the sleeve that determines axially location of the spindle is effectively isolated from significant axial stresses incident to clamping of the spindle. High pressure clamp energizing means rotatable with the sleeve is energized by fluid under relatively low pressure fed to the rotary sleeve assembly by a fluid supply collar which permits high speed rotation of the sleeve without wear or deterioration of the structure. |

Spindle Orienting and Drawbolt Malfunction Sensing Machine Tool Control System
|
Jack A. Wohfeil |
Fond Du Lac, Fond Du Lac County, WI |
Abstract:
A machine tool control system with control circuits for arresting rotation of a machine tool spindle in a fixed rotary orientation position where a draw-bolt used to secure work tools in the spindle is rotatable relative to the spindle to release one work tool and grip another and control circuit for sensing any failure of the draw-bolt to properly rotate relative to the spindle. The same rotary position transducer provides signals representing draw-bolt rotary position, and, when the spindle is rotating, spindle rotary position and spindle rotary speed, and such signals are utilized in the control circuits both to delay actuation of the spindle arresting mechanism until the spindle arrives at the orientation position below a predetermined creep speed and to sense any failure of the draw-bolt to rotate properly relative to the spindle. |

The digital signal is converted directly into an analogue signal which varies accurately in phase, relative to a reference wave, by direct digital comparison of the command number with a digitally signaled reference number which cyclically changes in synchronism with the reference wave. The reference wave is utilized to create a feedback signal which varies in phase, relative to such reference, according to the sense and extent of the displacement of the movable element, and which is compared with the phase variable commanded signal to create a polarized error signal applied to a servomotor coupled to drive the movable element. |

Machine Tool Having Longitudinally Adjustable Machining Spindle Hydraulically Clamped for Operation
|
Gordon H. Jones |
Van Dyne, Fond Du Lac County, WI |
Abstract:
A machine tool having a longitudinally adjustable machining spindle carried by a rotary spindle sleeve and securely clamped releasably within the sleeve by a clamping bushing encircling the spindle with very little maximum clearance therebetween and having an interference fit with encircling structure on the sleeve so that the clamping bushing has a high residual stress in compression even when released from the spindle for longitudinal adjustment of the latter with the consequence that high hydraulic pressure applied to predetermined areas of the external surface of the clamping bushing effects hard compressive contact with the spindle of bushing structure opposed by the hydraulic pressure and adjacent structure of the hushing unopposed by the hydraulic pressure is continuously forced into hard compressive contact with the encircling structure on the sleeve to the end that the spindle when clamped in a longitudinally adjusted working position is securely supported radially in a position precisely coaxial with the spindle sleeve. The clamping bushing is assembled with the encircling structure on the spindle sleeve with which it has a marked interference fit by forcing the bushing longitudinally into the encircling structure thus producing a high compressive stress in the bushing, which is subsequently ground internally with great precision to fit closely around the spindle with minimal clearance for longitudinal adjustment of the spindle. |

Apparatus for Numerical Signaling of Positions, Including Digital to Analog Converter
|
Thomas B. Bullock |
Fond Du Lac, Fond Du Lac County, WI |
Abstract:
Apparatus for producing digital signals which numerically represent at all times the position of a movable element as it moves to different positions along its path oftravel. The digital signals in the form of bi-level voltages are produced in a multidecade reversible counter to represent the position numerically in binary coded decimalnotation. These signals are supplied to a digital-to-analog converter whose analog output, corresponding to the represented position, is supplied to a resolver type transducer mechanically coupled to the element. The transducer produces a discrepancy signal representing the sense and extent of any difference between the numerically represented position and the actual position of the element. So long as the discrepancy signal exists, pulse producing means are enabled to supply pulses to the counter so as to correctively change the number signaled by the counter until the difference and the discrepancy signal are reduced substantially to zero. The closed loop correction is very rapid, so for practical purposes the number digitally signaled by the counter always represents the actual position of the movable element. The digital-to-analog converter here disclosed is the type which produces sine and cosine function signals for excitation of a resolver type transducer. This converter is characterized by cross-coupling of the outputs and inputs of two algebraic combining devices such as operational amplifiers, by static switching means responsive to input signals digitally representing a changeable number, and by simple resistors selectively rendered effective to produce AC signals proportional to sine and cosine functions of the sums of angles corresponding to higher and lower order portions of the changeable number.

No. 3,540,346 and entitled "Machine Tool Having Longitudinally Adjustable Machining Spindle Hydraulically Clamped for Operation." In addition, the spindle clamping apparatus of the present invention also relates to a machine tool of the general type described and claimed in U.S. application filed on 12 July, 1968 now U.S. Pat. No. 3,516,328 and entitled "Machine Tool with Longitudinally Adjustable and Hydraulically Clamped Rotary Machine Spindle."
Abstract:
A machine tool having a longitudinally adjustable machining spindle carried by a rotary spindle sleeve and securely clamped releasably within the sleeve by a clamping bushing encircling the spindle. The clamping bushing is force fitted within the encircling structure of the sleeve so that residual compressive stresses are established. The sleeve and clamping bushing define an elongate, annular chamber, cylindrical in nature, which is disposed intermediate the ends of said bushing and sealed to render same a fluid chamber. Fluid pressure means are associated with said chamber to provide fluid under pressure, whereby said clamping bushing is restricted circumferentially to effect hard compressive contact with a machine tool spindle. The clamping arrangement utilizes a relatively thick, stiff clamping bushing structure in conjunction with a plenum chamber that is extremely narrow in section, whereby numerous advantages over prior clamps are attained. |

Preload Spindle Bearing for Machine Tool
|
Charles R. Maastricht |
Fond Du Lac, Fond Du Lac County, WI |
Abstract
A spindle mounting for a machine tool adapted to apply a predetermined light preload to the spindle bearings during high-speed operation and a predetermined higher preload during low-speed operation. The preload mechanism includes a pair of axially aligned hydraulically actuated pistons disposed on opposite sides of one of the outer bearing races. The pistons have a relatively narrow annular shape and do not extend radially outward substantially beyond the bearing, thereby minimizing the headstock space required. The outer periphery of each spindle bearing is formed with annular grooves through which a cooling fluid may be circulated for more efficient cooling of the bearings. Such cooling grooves also permit the bearings to be directly mounted in the headstock housing without containment in an intermediate cooling sleeve, thereby providing more accurate spindle support. |

This application is a division of United States application 12 filed July, 1968, now U.S. Pat. No. 3,516,328.
Abstract:
A machine tool comprising a machining spindle adjustably extensible longitudinally within a rotary support sleeve and releasably clamped to the sleeve by a clamping bushing applied by high pressure hydraulic energizing means positioned on the spindle sleeve in such manner that application of the camping bushing does not change the load on precision bearing means used to support and precisely locate the sleeve radially and axially and does not apply significant axial stress to the structure that functions to determine the axial position of the spindle to the end that the spindle is clamped for rotation precisely in the exact axial position desired. The clamping bushing has an axial position proximate a precision bearing that locates the sleeve and spindle axially with precision and the high fluid pressure clamp energizing structure that rotates with the sleeve and energizes the clamp hydraulically is situated on the sleeve so that the portion of the sleeve that determines axially location of the spindle is effectively isolated from significant axial stresses incident to clamping of the spindle. High pressure clamp energizing means rotatable with the sleeve is energized by fluid under relatively low pressure fed to the rotary sleeve assembly by a fluid supply collar which permits high speed rotation of the sleeve without wear or deterioration of the structure. |

Power Tool Turret Assembly
|
Russell D. Bouffiou |
McFarland, Dane County, WI |
Abstract:
A machine tool turret head, more particularly a power operated turret head, is provided with fluid power actuated toggle means for axially clamping the turret head to the machine tool ram or saddle. When a wedge member is withdrawn from a position between the toggle members, the turret head is released from a clamped work position and allowed to slide axially for a limited distance along a turret head stem. Logic circuitry and a resolver are employed to cause a motor and drive train to rotate the turret head and to locate the head via the most expeditious route within the predetermined initial angular tolerance limits of a new work position. The wedge member is then reinserted between the toggle means to move the turret axially back along the stem, and reclamp the turret in its new work position. A lost motion coupler is included in the drive train to allow the turret head to rotate slightly as it moves into its clamped position without damage to the associated drive train or other parts. |

Acceleration Deceleration for Numerical Control
|
John K. McGee |
Houston, Harris County, TX |
Abstract:
Methods and apparatus for accomplishing fully automatic acceleration/deceleration in a numerical control system of the iterative computation type such that disclosed and claimed in applicant's co-pending U.S. application which issued on 11Apr., 1972 as U.S. Pat. No. 3,656,124. Any step-change in the velocity called for by a multi-axis program of movement for a movable member is accomplished wholly automatically and at a predetermined rate dV/dt (acceleration or deceleration) which is readily changed to be within the capability of driving servos and such that overshoot and undue time stretch are avoided. In particular, velocity is controlled by iteratively changing position servo command numbers XSC and YSC (for two axes) by amounts .DELTA.X and .DELTA.Y during each of very short, successive time periods .DELTA.T, where .DELTA.X and .DELTA.Y are computed during each period to be proportional to a desired velocity number PVA. Whenever a new velocity is to be put into effect, a second velocity number PVC may be abruptly changed by a large amount, and thereafter the desired velocity number PVA is incremented by a predetermined amount .DELTA.V during each period .DELTA.T until PVA becomes equal to PVC, so that the acceleration or deceleration value is .DELTA.V/.DELTA. T. The quantity .DELTA.V is preferably changed as a monotonic function of the velocity difference PVC-PVA, and to reduce time stretch may be made proportional to that difference. By "looking ahead" with computations which determine the distance which will be traveled by the movable member during deceleration from a given velocity to a lower one, the deceleration is started at an instant which results in the lower velocity being reached almost exactly at the time a given path segment is completed. The apparatus and methods are carried out with a data processing system which includes a time-shared arithmetic computer, and are equally effective whether the system is operating to perform linear or circular interpolation. |

Adaptive Machining

Foreign Application Priority Data in Great Britain, 09 Nov., 1971.
Abstract:
Methods and apparatus for adaptively controlling a machine tool to provide optimized instantaneous performance as unforeseen or unforeseeable changes in cutting conditions occur; --characterized by a continuous search out of and back into a permissible area defined by constraint boundaries in the cutter speed vs. feed rate (V vs. R) plane. The method and apparatus always adjust the cutter speed and feed rate to conditions of optimized economic operation (e.g., minimum cost or minimum time)--but subject to other limitations of the machine tool, the cutter and the workpiece material--because one such boundary defines the optimum values of cutter speeds and feeds representing minimum cost or minimum time per unit length of machining. The latter boundary is established by straightforward use of empirical contants, available in the literature or readily determined by known techniques, associated with the well known modified Taylor equation. By sensing machine tool variable and signaling actual values of a plurality of operating parameters, the output rate of the machine tool is increased until the economic restraint, or some other inherent limitation restraint, is reached. The corrective action to remove any constraint violation is based upon a grouping of the several signaled parameters according to the shapes of the respective boundary lines corresponding thereto in the V, R plane, so that the method steps for effecting correction of any constraint boundary violation are relatively few in number and may be carried out by novel apparatus which is simple and practical.

Automatic Deceleration to Zero Velocity in Iteratively Computing Numerical Control Systems
|
John P. Connors |
Fond Du Lac, Fond Du Lac County, WI |
Abstract
Methods and apparatus embodying improvements in numerical control systems of the genus disclosed in United States application filed 15 Mar., 1971 in the name of John K. McGee, now U.S. Pat. No. 3,727,191 and particularly for simplifying and rendering more accurate the look-ahead sensing and automatic deceleration of a movable element to zero velocity as it reaches a commanded end point position. The velocity of an element moving toward a numerically defined stopping position is successively reduced to a predetermined fraction or percentage of its previous value during each iteration period once deceleration is initiated in response to comparison of the remaining distance to the end point with a distance which will be traveled during the deceleration phase. The latter distance is found by simple computations involving essentially a constant which is derived directly from the said selected, predetermined percentage. As a result of reducing the velocity by the same predetermined percentage during successive equal periods, the velocity falls in a substantially exponential fashion and the deceleration is thus smooth but consumes relatively little time |

Reduction of Servo Following Errors in Position and Velocity Control Systems of the Iteratively Computing Type
|
James B. Simon |
Fond Du Lac, Fond Du Lac County, WI |
Abstract:
Methods and apparatus for reducing following errors in the servo drives of positioning and velocity control systems wherein the commanded position is signaled and updated by increments .DELTA.X during each successive equal time periods .DELTA.T, --so as to cause the controlled member movable along any axis X to travel at a velocity V.sub.x = .DELTA.X/.DELTA.T. The commanded position is updated by iterative computations at least once during each period .DELTA.T, and the .DELTA.X increments to be used for such updating are numerically signaled and can be changed as frequently as once during each period .DELTA.T. In order to create a feed forward signal for application to the servo in a sense additive to the position command signal, the digitally signaled number .DELTA.X is converted into a corresponding analog signal. In the preferred arrangement, this conversion is accomplished by a counter which is preset to the number .DELTA.X at regularly recurring instants and arranged to count down whenever the number held in the counter is other than zero. A decoder responsive to a predetermined count, for example zero, not only terminates the counting action until the next presetting but also produces a constant frequency, variable duty cycle square wave having an average or dc. value proportional to the number .DELTA.X and which serves as an accurate feed forward input to the servo. |

Abstract:
A power operated rotary draw-bolt for clamping tools in a machine tool spindle tool adapter socket in which the tool coupling end of the draw-bolt includes a threaded fitting which is replaceable through the socket end of the spindle.
Background/Summary
(1) This invention relates to power draw-bolts for releasably securing tool adapters to machine tool spindles. My U.S. Pat. No. 2,924,152 discloses a power operated rotary draw-bolt of the type to which the present invention is applicable. This patented draw-bolt has proven to be commercially successful. However, after many thousands of operating cycles, the threads on the outer end of the draw-bolt which engage the tool adapter sometimes wear out requiring replacement of the entire draw-bolt. Removal of the draw-bolt, which must be done from the rear end of the spindle, requires partial dismantling of the machine. This in turn requires that there be sufficient space between the machine and adjacent structures to allow the lengthy draw-bolt to be extracted from the spindle. Thus, replacement is time consuming and costly. The frequency of replacement has been intensified when the draw-bolt is used on machines operating automatically or semi-automatically under numerical control. |

Alleviation of Delays and Inaccuracies in Machining by the Constant Surface Feet Per Minute Mode
|
William H. Mack |
North Fond du Lac, Fond du Lac County, WI |
Abstract:
Methods and apparatus for causing a turning machine tool to operate with selectable but "constant surface feet per minute" (CSFM) under the control of an iteratively computing numerical control director, and characterized by anticipation of the necessary spindle or table r.p.m. which will be required at the start of a cut, such that as the cutter is rapidly approaching a workpiece, the spindle or table is accelerated to that required speed, thereby to substantially eliminate the delay which would be necessary to wait for the required speed to be reached with spindle or table servo motors of limited power driving loads with high inertia. The invention is specifically embodied in methods and apparatus for substituting (in lieu of signals representing the actual radius of the cutter from the workpiece center) signals representing the radial distance from the work center which the cutter will reach at the end of a rapid traverse positioning motion and while that positioning motion is being executed in the steps and apparatus by which the table or spindle speed is made inversely proportional to a signaled radius value. |

Norbert Kolell |
Fond Du Lac, Fond Du Lac County, WI |
The present application is a division of co-pending U.S. application filed 09ug., 1972 in the name of Norbert C. Kolell and assigned to the assignee of this application.
Abstract:
Methods and apparatus relating to either point-to-point or contouring control of the movable members of a machine tool, wherein two or more of such members are movable along a common axis relative to a base. In order to accept end-point commands numerically expressed in part coordinate along the common axis with reference to an origin in fixed relation to a workpiece or part mounted on the first such member, even though the servo controls or actual positioning operations can only act to bring the two members to positions measured in base coordinates with reference to a second origin fixed in relation to the base, a first signaled number representing the desired position of the second member in base coordinates is subtracted from a second signaled number representing the desired position, in part coordinates, for the first member. Such subtraction creates a changeable signaled third number representing the base coordinate positions to which the first member is to be moved under servo control. When the second member is moved, its displacement from one position to the next is added to the aforesaid and second numbers, so that the third number does not change but the first number does change to provide a numerical representation of the base coordinate position to which the second member will be moved under its servo control.

Abstract:
Numerical control for machine tools and the like of the genus described in McGee U.S. Pat. No. 3,656,124. Improvements are here described for digital computations and control which cause a tool or cutter to follow successive path segments programmed in workpiece edge coordinates, even though the servos operate to control the motion and positioning of the center of a cutter having a finite and unforeseeable radius. Additionally, automatic smooth transitions from segment to segment of the path are effected with a tangent fillet machined on the workpiece which has a radius equal either to that of the cutter or a value which is designated as a single numerical value in the program command data. |

Position Control System with Plural Signal Transmission Through Common Inductive Device
|
James B. Simon |
Fond Du Lac, Fond Du Lac County, WI |
Abstract:
A position-controlling system associated with one or more movable members and utilizing a resolver type inductive coupling device such as a "linear Inductosyn," characterized by the transmission of alternating voltages having more than one frequency through the device. In the preferred form, analog signals of first and second frequencies are applied to excite two sets of input windings and the signal from a single output winding is split into its frequency components so as to produce error signals for driving two members to commanded positions along a common path; and an input of third frequency is superimposed upon the excitation for one set of input windings with the subsequent separation of that frequency from the output signal to monitor and confirm the operability of the inductive device and its associated components. The simultaneous control of two members may be employed without the monitoring, or the monitoring may be employed in a system controlling the position of a single member. |

Two Pressure Counterbalance System for Machine Tool Headstocks
|
Donald J. Cayen |
Fond Du Lac, Fond Du Lac County, WI |
Abstract:
A counterbalance mechanism for a vertically movable machine tool headstock in which the net counterbalance force applied to the headstock is the same for both upward and downward movement of the headstock so that the accuracy of the spindle alignment is not disturbed by such movement. The counterbalance mechanism includes a hydraulic control system which automatically provides a greater pressure to a hydraulic counterbalance cylinder during raising movement of the headstock than during lowering movement so that difference in forces exerted by the counterbalance cylinder as a result of said pressure differential compensates for frictional resistive forces in the counterbalance mechanism and thereby enables the same net counterbalance force to be applied to the headstock. |

Turret Lathe
|
Richard C. Rudolph |
Fond Du Lac, Fond Du Lac County, WI |
Abstract:
A horizontal bed turret lathe including a slant carriage adapted to achieve the advantages of a slant bed configuration while avoiding the disadvantages thereof. The slant carriage is mounted on a pair of horizontal bed ways offset to the rear of the spindle axis, and includes a pair of inclined slide ways for supporting a tool slide. A turret mounted on the tool slide has a pair of toolholders arranged in stacked configuration on the turret axis. For reducing interference from non-working tools and the turret assembly itself, the turret axis is skewed with respect to the spindle axis. To compensate for the skew of the turret axis, the toolholders are frusto-conical in shape, the degree of conical taper allowing each tool to be indexed to a normal operative position. An orderly tool arrangement is achieved by mounting end working tools in the upper toolholder and turning tools in the lower toolholder, the overall configuration allowing both end working and turning tools to operate up to the face of the chuck. Additionally, a tailstock may be conveniently provided on a pair of auxiliary ways, the overall configuration minimizing interference from the tailstock. The slant carriage is further stabilized by folding the slide drive and slide counterbalance assembly back into the carriage thereby lowering its center of gravity. |

Abstract:
An improved final servo control for numerical control systems of the type which perform linear and/or circular interpolation by iterative updating of commanded position signals. The improvements are embodied in means to sense when the servo loop has had an offset error introduced by drift or aging of the final amplifier or similar components, together with means for progressively and automatically removing such error; and by means to avoid attempts at extreme acceleration or deceleration beyond the ability of the servo power element (motor) to accomplish, --by creating from an iteratively updated primary position command signal, whose rate of change may suddenly alter by a wide margin, a secondary position command signal which varies ultimately by the same amount but at a lesser rate of change. |

Block Type Cutting Tool With Positive Clamp for Insert Blades
|
Harvey R. Plummer |
Fond Du Lac, Fond Du Lac County, WI |
Abstract:
A block type cutting tool with insert blades of the throw away type, the block having pockets for mounting the inserts and clamps movable into the pockets for locking the inserts in place. Each insert includes a groove formed centrally thereof and running generally parallel to one of the locating surfaces of the pocket for engaging a tip portion of the associated clamp. The groove is wider than the tip so that locking of the clamp first causes the tip to wedge the insert into the pocket, following which the tip engages the lip of the groove to firmly draw the wedged insert against a locating surface. This arrangement more positively holds the insert against displacement when the tool is withdrawn, provides a perceptible stop indicating the clamp is fully locked, and, in cases where radial insert adjustment is provided, helps to guide the insert to prevent cocking. |

Interruptable Numerical Contouring Control System with Return to Path Safeguards
|
Bruce R. Beadle |
Fond Du Lac, Fond Du Lac County, WI |
Abstract:
A numerical control contouring system in which successive path segments are executed according to successive blocks of command signals making up a path program, the system being interruptible at any time by a feed-hold signal to stop the controlled movable member at a random point on the path. The system is characterized by the improvement of preventing the system from resuming normal operation unless and until the member is returned to the path stopping point after it has been, for any reason, displaced therefrom under manual control or the like. In one embodiment, the axis component displacements of the member from the stopping point are represented by signals created and displayed, and the operator's restart pushbutton switch is rendered ineffective until the displayed displacement signals are reduced to zero. In another embodiment, the axis component displacement signals are utilized to create a non-program block of command signals, and means responsive to a restart signal first cause the member to be moved back to the path stopping point before the system is automatically restored to normal operation. In a third embodiment, after each movement of the controlled member following its arrival at the stopping point, the axis components for that movement are signaled and stored, and means responsive to a restart signal first utilize such stored signals to execute such movements in reverse order and senses to return the member to the path stopping point, and next restore normal operation of the system so that movement along the path is resumed. |

Servostatic Bearing System With Variable Stiffness
|
Sharad M. Marathe |
Fond Du Lac, Fond Du Lac County, WI |
Abstract:
The invention provides a hydraulically sealed, variable stiffness servostatic bearing system for use in machine tools and between any other loaded surfaces. Bearing pads operate between two relatively movable surfaces. A pilot valve senses changes in the bearing surface spacing and communicates by pressure variations with a diaphragm controlled restrictor valve. The diaphragm controlled restrictor valve apportions proper amounts of hydraulic fluid at proper pressure to the bearing pads. The combination results in a bearing system the stiffness of which is adjustable from positive to infinite to negative by the source hydraulic pressure to the diaphragm restrictor valve. A lift bladder and a modular bearing pad assembly to facilitate easy and quick installation and removal of bearing pads are also described. |

Abstract:
A harness for an electromagnetic transducer such as an INDUCTOSYN-type slider includes four separate series of thin flat U-shaped connectors stacked on top of each other for connecting the ends of the U-shaped conductors on the slider to each other in the desired pattern. Each separate series of connectors are separated from each other by a thin film of insulating material, with the ends of each connector projecting beyond one edge of the insulating film to form tabs which are aligned with the ends of preselected U-shaped conductors for connection thereto. The end tabs of the connectors may be joined to the conductors by a single soldering operation, and the entire harness assembly may be prefabricated by laminating the four series of connectors to each other. The connectors are formed by printed circuit techniques. |

Digital Computer Structure Providing Arithmetic and Boolean Logic Operations, the Latter Controlling the Former
|
John P. Conners |
Fond Du Lac, Fond Du Lac County, WI |
Abstract:
A digital computer of relatively simple and efficient structural organization which is capable not only of conventional arithmetic operations according to a program but also of (i) performing chained Boolean logic processing on any selected bit of any of various selected words held in memory, (ii) using the logic processing result by storing it at any selected bit location in any of various selected words held in memory, and/or (iii) causing different, predetermined instructions within a program to have their execution dependent upon the results of previously performed single bit logic processing. The logic processing is carried out in response to specially coded instruction words which may be randomly interspersed between conventional arithmetic instruction steps within an overall program. Existing registers and apparatus components necessary for conventional arithmetic operations are utilized in large measure to carry out the routing of signals to and from the logic processor, and very little added hardware is required to create the logic processing, storing, and dependent conditioning. |

System for Entering Information Into and Taking It From a Computer From a Remote Location
|
Bruce R. Beadle |
Fond Du Lac, Fond Du Lac County, WI |
Abstract:
A system for transmitting binary instruction or data words to or from a computer by control from a home base remote from the computer site, and characterized by the entry of signals into the computer or the extraction of signals from the computer performed by apparatus which directly connects to the computer console manual switches and indicator lights. A single telephone line forming two simultaneously active channels transmitting time-spaced pulses in opposite directions, by modems known in the art, is used as the communication link. A special purpose microcomputer directly connected to the main computer console acts figuratively to actuate the console push button switches in response to pulse train signals received from home base and representing single bits or multibit words. It returns to the home base a rapidly iterated and updated pulse train representative of the status of all console lights. The system includes another computer at the home base with a duplicate, reflective console like that of the main computer. The apparatus at the home base computer responds to binary messages to the main computer, due to actuation of the reflective console, with the same effect as if it were being used and observed at the computer site. |

|
John P. Conners |
Fond Du Lac, Fond Du Lac County, WI |
This application is a division of U.S. application (now U.S. Pat. No. 4,212,076) filed 24 Sept., 1976 under and with benefit of 35 U.S.C. 120, 121. That parent application and issued patent will hereinafter be called "the Parent Case". The drawings and specification of the Parent Case are here incorporated by reference to provide background of or essential material for the invention and to illustrate one environment in which the invention here claimed finds advantageous use.
Abstract:
A clocked digital Boolean processor which responds to operation code signals and to successive single bit input (operand) signals to drive a single bit accumulator to output the successive answers of chained Boolean operations. The hardware elements are configured such that no feedback of the accumulator output (the previous answer) is required because the logic circuits determine the setting or resetting of the accumulator regardless of what the previous answer was and yet such that the new answer represents the result of a LOAD, AND, OR or EX-OR operation performed as if the input operand and the previous answer were taken as two operands. |

Pallet Transfer System
|
Leonard A. Miller Jr. |
Fond Du Lac, Fond Du Lac County, WI |
Abstract:
A workpiece handling system is disclosed. The system includes a generally centralized pallet handling stand, and a number of pallet-accepting stations. These stations can be associated with machine tools such as vertical turret lathes or horizontal boring machines or other machine tools. The station can also be a relatively simple pallet storage station. Alternatively, the station can comprise a cart upon which a pallet can be deposited for movement to other parts of the factory. The pallet transfer station includes a foundation, and a base rotatable upon the foundation. A ram is translatably slidable on the rotatable base. A latch is reciprocable upon the ram. To transfer a pallet from one station to another, the base is angularly indexed into general alignment with the first work station. A shot pin device effects final, precise alignment of the ram with the work station. The ram is then radially advanced into engagement with the work station. A Vee-shaped member effects alignment of the work station with the ram. The latch is then advanced to the work station, and engages the pallet. The latch then draws the pallet over a safety latch and into a relatively centralized position on the ram. The ram is then withdrawn to a relatively centralized position on the base. The base can then be angularly indexed into general alignment with the other work stations. |

Drill Grinding Machine
|
Richard L. Schroeder |
North Fond du Lac, Fond du Lac County, WI |
Abstract:
A drill grinding machine employs independent servo motors for drill rotation, drill lift, and drill feed. The three motors are connected through respective suitable drive mechanisms to a tubular spindle that is rotatably mounted within a work head. The work head contains a hydraulic clamp for selectively chucking and releasing a drill holder. A drill is gripped in the drill holder such that the drill point is proximate a grinding wheel. The drill, lift, and feed motors are actuated to rotate the drill about its longitudinal axis and to move the drill point along a predetermined cyclical path of contact with the grinding wheel to grind a selected point. Combinations of points may be ground on a single drill by suitably controlling the lift and feed motors. A timing pad adjustably mounted to the machine housing cooperates with the lift and feed motors and the work head clamp to enable the drill to be manually timed prior to a grinding cycle. Drill rock is selectively available through spring loaded contact between the work head and a hardened strip that is rotatably mounted in the machine housing. |

Automatic Assembly System
|
James R. Spece |
Milton, Rock County, WI |
Abstract
An automatic assembly system transports workpieces to a work station whereat the workpieces are processed into an assembled product. The automatic assembly system conmprises a monorail that defines a path above the work station. A trolley travels along the monorail supporting a workpiece carrier by means of a pair of latches pivotally connected to the trolley. A lowerator mechanism is mounted to the monorail above the work station. When a trolley stops above the work station, the lowerator mechanism thereat operates to lift the workpiece carrier from the trolley latches. The trolley latches retract and the lower mechanism then lowers the carrier and workpieces to the workstation without lowering the trolley or the monorail. A safety interlock prevents uncontrolled lowering of the carrier and workpieces. Tooling trays suitable for holding different sets of workpieces index in directions parallel to the monorail path to bring to the work station the tooling tray required for the particular workpiece being lowered to and processed at the work station. |

Rotate/Translate Conveyor Module
|
Paul D. Terpstra |
Janesville, Rock County, WI |
Abstract:
A rotate/translate conveyor module enables a workpiece to be selectively rotated and translated between adjacent sections of a conveyor without having to be lifted above the plane of the adjacent conveyor sections. The rotate/translate conveyor module comprises a plurality of roller modules that are arranged along the path of the workpiece. Each roller module has at least one roller that is driven by an independent electric motor. The rollers of the roller modules support the workpiece in the same plane as the rollers of the conveyor sections. In one embodiment, four roller modules are symmetrically located about the workpiece path, with the longitudinal axes of the rollers intersecting at 90 degrees and at a point on the workpiece path. By operating the electric motors in different combinations of directions, four translational and two rotational motions can be imparted to the workpiece. The conveyor module is thus able to accept a workpiece from an adjacent upstream conveyor section and selectively reorient it by rotating it on the conveyor module and then translate the workpiece downstream to an adjacent downstream conveyor section. The downstream conveyor section may be in line with the adjacent upstream conveyor section, or it may be perpendicular thereto. Side guide mechanisms guide the workpiece as it is translated along the conveyor module. Center guide mechanisms prevent translation of the workpiece during rotation thereof on the rollers. |

Method of Cracking a Connecting Rod
|
Larry T. Becker |
Milton, Rock County, WI |
Abstract:
Apparatus and method for cracking a connecting rod comprises long and short semi-circular dies. The dies include self-contained means for biasing their flat surfaces together to enable them to be inserted through the connecting rod bore. The long die is supported on both sides of the connecting rod. The connecting rod bore initially contacts only the long die. A force generating tool passes through the long die and contacts the flat surface of the second die. The tool operates to separate the two dies against the self-contained biasing means such that both dies contact the connecting rod bore. The tool applies a force to the second die along a plane parallel to the longitudinal axis of the connecting rod bore. The force is sufficient to crack the connecting rod. The force may be either an impulsive force or a relatively slowly applied force. After cracking, the tool is withdrawn from the long die, and the self-contained biasing means biases the two dies against each other ready for insertion into another connecting rod bore. |

Bushingless Workhead
|
Jerry G. Warner |
Slinger, Washington County, WI |
Abstract
A bushingless workhead comprises a flexible drill collet inside a flexible chucking collet. The chucking collet has external frusto-conical surfaces on the ends thereof that mate with corresponding frusto-conical surfaces on a pair of pistons. The pistons are slidable within a housing away from each other to apply opposed forces to the chucking collet. The forces cause the chucking collet to collapse and to also collapse the drill collet to grip a tool inside the drill collet. One piston applies a greater force on the chucking collet than the other piston. The chucking collet is thus forced to move longitudinally in one direction, and it abuts a fixed reference surface that repeatably locates the chucking collet during each tool gripping operation prior to the chucking collet collapsing to grip the tool. |

Automatic Drill Loader
|
Kenneth H. Allen |
Hendersonville, Henderson County, NC |
Abstract:
An automatic drill loader is used with a drill grinding machine to automatically present drills to the drill grinding machine workhead for being ground thereat and to carry ground drills to a storage receptacle. The automatic drill loader comprises a magazine, a timing station, and two sets of grippers. The magazine stores a quantity of drills, which may have stepped shanks. The magazine is adjustable to suit drills of different lengths and diameters. The magazine presents one drill at a time to a staging station. A load gripper grips the drill at the staging station and conveys it to the timing station, whereat the drill is linearly and angularly oriented. The load gripper then transports the drill to the drill grinding machine workhead. Simultaneously, an unload gripper carries a ground drill from the drill grinding machine workhead to the storage receptacle. After the load gripper has transported the timed drill to the drill grinding machine workhead, the load gripper returns to the staging station to grip another drill. Simultaneously, the unload gripper returns to the workhead to grip and remove the finished ground drill thereat. The cycle continues automatically until all the drills in the magazine are ground. |

Rotational Motion Limit Detector System and Method
|
Philip J. Finet |
Milwaukee, Milwaukee County, WI |
Abstract:
A system for detecting a limit of acceptable rotation for a joint is disclosed. The system includes a support that supports the joint and keeps its pivot point substantially stationary with respect thereto. The system also includes an extensible leg connected to the joint. A contoured member is mounted adjacent the extensible leg and has a surface shaped as a portion of a sphere. The contoured member is located so the pivot point of the joint substantially coincides with the center of the sphere and the periphery of the contoured member corresponds to the limit of acceptable rotation for the joint. Thus, as the leg pivots, the contoured member also moves a similar amount. A detector is used to detect the periphery of the contoured member surface and to assist in preventing further rotation of the joint in that direction. |

Linear Pallet Stop
|
Ronald J. Sam |
McFarland, Dane County, WI |
Abstract:
A linear pallet stop smoothly decelerates a heavy pallet propelled by a conveyance system in a downstream direction and stops the pallet at a predetermined location. The linear pallet stop comprises a catch arm that is translatable and rotatable between three positions. At the first position, the catch arm first end is in the pallets path to be contacted by the pallet and translated in the downstream direction by the pallet momentum. The downstream translation is resisted by a fluid circuit acting through a cylinder and a slide that is in support contact with the catch arm. A stop surface on the catch arm strikes a fixed surface on the conveyance system at a second position of the catch arm. By retracting the slide with the fluid cylinder when the catch arm is in its second position, the catch arm rotates to a third position whereat its first end is out of the pallets path. The catch arm is guided for translation and location by cam followers that are captured within slots in housings. After the pallet has been propelled further downstream, the cylinder is operated to extend the slide and push the catch arm in the upstream direction and return it to its first position. |

|
Joseph Zink |
Beavercreek, Greene County, OH |
Abstract:
A CMM control system which presents a three-dimensional graphic representation to the operator showing the active probe tip recognized by the CMM software. The controller software determines whether a motorized probe head is present and the exact location the probe tip. By using three-dimensional vector graphic routines, the controller software presents a graphic display of the probe relative to the machine's coordinate system. This technique minimizes the occurrence of measurement errors which could be introduced by the unwary operator who inadvertently used CMM data taken with an unrecognized probe tip. |

Abstract:
A coordinate measuring machine (CMM) is disclosed having improved manufacturability and low cost while maintaining high performance standards. The CMM includes a polymer composite gantry-style base incorporating a three-point support configuration in the X, Y, and Z axes. The X-beam is hollow, has a horizontal cross-sectional orientation, uses a passive ventilation technique, and is attached to the bearing at one end by a compliant mount. The Z-axis probe shaft incorporates a combined counterbalance/drive assembly and a compliant secondary rail guide mechanism. The X-axis and Y-axis drive screws have angular alignment capability using a spherical washer configuration. This combination of features serves to minimize non-repeatable errors and enhance the manufacturability of the CMM, providing substantial improvements in CMM design and construction. |

Method and Apparatus for Determining Tolerance and Nominal Measurement Values for a Coordinate Measuring Machine
|
Joseph H. Zink |
Beavercreek, Greene County, OH |
Abstract:
A method of operating a coordinate measuring machine (CMM) provides the operator with the ability to automatically set the tolerance value of the part measurement based on preset conditions, and make an educated guess or estimate of the nominal part value during the measurement. This nominal estimation technique is based on the actual measurement value taken by the CMM, and the information supplied about the tolerance limits. This estimation technique of the present invention makes it much easier for the operator to measure the part and produce a report, since it significantly reduces the amount of operator keystroke information required to be manually input via the keyboard. |
