摘要： An apparatus for feedback adjusting the working condition of a working machine on the basis of measured dimensions of processed workpieces, including a determining device for determining automatic and manual compensating values, and an applying device for applying the automatic and manual compensating values (Ui, U') to a machine controller for adjusting the machine working condition. The determining device determines the automatic compensating value on the basis of first or second estimated dimensional values of the workpieces obtained in an automatic compensating cycle. Each first estimated dimensional value is a sum of an actually measured dimension (X) of the workpiece and a last compensating value (U'), while each second estimated dimensional value is a sum of the actually measured dimension, the last compensating value and a previous compensating value (Ui-2, Ui-1) preceding the last compensating value. Also disclosed is a method of feedback adjusting the machine working condition.

摘要： A machine tool system having an adjustable implement mounted in a holder or chuck and moveably positioned relative to a moveable workpiece support, wherein implement adjustments are produced by controlled differential motion between the implement holder and an adjustment fixture on the workpiece support. The support is moved to engage the implement in the fixture, from which state further relative movement unlocks an implement clamp and produces a desired adjustment in the implement. Typical implement adjustment applications would include setting of a boring bar cutting radius (or setting of a measurement gauge dimension). The adjustments can be performed open loop based on prior calibration of implement adjustment versus extent of support motion, or closed loop wherein an initial cut (or measurement) is made by open loop implement adjustment with subsequent adjustments based upon a measurement made of the implements effective cutting (or measurement) dimension. Desired incremental changes in cut (or measurement) dimensions are then effectuated through corresponding incremental support motion. Closed loop mesurement and adjustment iterations largely overcome implement dimension errors due to rechucking, thermal drifts, machine motion position offsets, implement or contact point phenomena effects, speed-related dynamic distortions, gradual implement/wear and implement/workpiece force compliance. These measurements for iterative adjustment can be made with manual or automated gauging systems, either separate or integral to the machine adjustable implement system. The implement adjustment mechanism can be provided with a substantial mechanical advantage to correspondingly increase accuracy in implement adjustment.

摘要： A tool holder incorporating a tool position compensating mechanism is disclosed, which includes a screw shaft axially slidably but non-rotatably supported in a tool mounting shell and formed with a cam surface. A rotary member is rotatably received and threadedly engaged with the screw shaft. A ring shaped internal gear and a reduction gear device including a planet gear are arranged to transmit rotation of a tool spindle to the rotary member at a predetermined reduction gear ratio. When rotated, the rotary member moves the screw shaft in the axial direction which causes adjustment of a tool position in the radial direction by the wedging action of the cam surface.

摘要： A size control apparatus for a machine tool having an in-process gauge device, a post-process gauge device, a calculating device and a compensating device. The post-process gauge device measures the workpiece machined under the supervision of the in-process gauge device and supplies the measured value to the calculating device. The calculating device derives an estimated value for a workpiece to be next machined from a predetermined number of measured values and ascertains a compensating value when the estimated value exceeds a control limit. The compensating device, when given the compensating value, shifts a null-point of the inprocess gauge device so that the finish size of the workpiece may be compensated.

摘要： The invention disclosed provides a device having means for emitting two beams of laser light in parallel and in contact respectively with an upper edge and a lower edge of a rotating cylindrical workpiece while under machining conditions such as in a lathe. The two laser beams hit the workpiece edges and then enter respective light receivers wherein diffraction images of the upper and the lower edges of the workpiece, which are sharpened by means of an optical filter, are defined on image planes formed with optical fibers. Intensity distributions of the diffraction images are converted into electric signals and processed in order to identify the diameter at the machining point of the workpiece. In case the difference between the detected diameter and a desired diameter exceeds a specified value of allowable error, a correction signal is transmitted from a provided means which causes a tool position controlling device to adjust the position of the tool, thus ensuring accurate turning of the workpiece within a specified tolerance while rotating in the course of machining.

摘要： A continuous-path numerical system controls the position of the cutter of a lathe with respect to the workpiece and the rate of rotation of the work spindle in accordance with a series of numerical commands encoded on a punched tape. Each command, in addition to position information, includes information relating to the desired rate of movement of the cutter over the workpiece in surface feet per minute and the desired rate of advancement of the cutter in terms of inches per revolution. The commands controlling the position of the cutter with respect to the center line of the spindle are continuously monitored and the quantity representative of the commanded separation is divided into the programmed surface feet-per-minute number to derive a number used to control the spindle motor drive. This system additionally calculates a feedrate number based on the incremental distances of motion along the X and Z axes called for by a particular command and the inches per revolution number. A pulse train generated by a transducer which senses the rate of rotation of the spindle is multiplied by this feedrate number to derive command pulse trains for DDA-type interpolators which generate control signals for the X and Z axes.

摘要： A feed rate and positioning control system for a machine tool is described which utilizes an electro-hydraulic pulse motor to move a grinding wheel support at preselected rates and for predetermined distances during a grinding operation. A control counter is arranged, via rate selecting switches, to select pulses of various predetermined pulse repetition rates for controlling the rates at which the electro-hydraulic pulse motor moves during a grinding operation. End point selecting switches and comparators are provided for determining the distances moved by the support during a grinding operation to signal the control counter to change rates or to start a dwell period. Dwell selecting switches, responsive to the control counter, are provided to establish the duration of dwell periods between application of selected rates and to signal the control counter at the end of each dwell period, including a spark out period at the end of the grinding operation.

摘要： A feed positioning control system having a non-volatile memory for a machine tool is described which utilizes an electrohydraulic pulse motor to move a grinding wheel support predetermined distances during a grinding operation. A control counter is arranged, via rate selecting switches to select pulses of various predetermined pulse repetition rates for controlling the rates at which the electro-hydraulic pulse motor moves during a grinding operation. End point selecting switches and comparators are provided for determining the distance moved by the support during a grinding operation to signal the control counter to change rates or to select a dwell period. Dwell selecting switches, responsive to the control counter, are provided to establish the duration of dwell periods between application of selected rates and to signal the control counter at the end of each dwell period, including a spark out period at the end of a grinding operation. The comparators are connected to pulse counting devices, which are responsive to the pulse input to the electro-hydraulic pulse motor. The pulse counting devices comprise five binary coded decimal up/down counters each having four-bit output. Each counter contains a distinct non-volatile memory device, each of which has four magnetic core storage elements, one for each bit. The system includes means for retrieving the data stored in the memory elements prior to shut will re-establish the output of the updown counters to the same point, subsequent to the power failure.
