摘要： PURPOSE:To generate easily a numerical control tape, by clamping the actual feed speed with an upper limit speed when a feed speed higher than the upper limit feed speed is commanded. CONSTITUTION:An upper limit speed VL for linear cut and an upper limit speed VC for arc cut are inputted to a comparison selecting circuit 102a of a controlling part 102. When a command speed Vi is read, the circuit 102a compares it with the upper limit speed VL or VC. As a result, if Vi

摘要： PURPOSE:To enhance the efficiency of quick return from the end point of a profiling route to its starting point, by storing the maximum value of present position in the profiling route and by causing the quick return to a position corresponding to the sum of the maximum value and a prescribed value. CONSTITUTION:The maximum heights Zma, Zmb of the surface of a medel MDL on profiling routes A, B extending from the starting point of profiling to its end point are stored. Quick return in the direction of an axis Z is effected to points of Zma+alpha, Zmb+alpha to perform return from the ending point to the starting point to shorten an unnecessarily long return route. Explaining with a block diagram, the outputs of position detectors PCX-PCZ are irreversibly counted at CUNT to indicate a present position. Supposing that a profiling direction is expressed by X and approach is expressed by Z, a servomotor MZ is driven depending on the displacement of a stylus ST to machine a workpiece W along the model MDL by a cutter CT. A processor CPU stores the maximum value of a counter CUNTZ in a register A.

摘要： PURPOSE:To perform highly precise contour with a memory having a small capacity, by renewing the contents in a memory, when a new abrupt change point is detected adjacent an abrupt change point of a model form along a contour path, to be the position as an abrupt change point. CONSTITUTION:When the form of a model MDL is changed abruptly, a synthetic displacement signal epsilon becomes large whose magnitude above a preset magnitude is detected in a comparator circuit COMP2, and a abrupt change signal MV is added to a data input apparatus DI. If the contour is on an X-Z surface and when the MV is obtained, since the contents of reversible counters CUNTX, CUNTZ will indicate the position of the abrupt change, by control of a processor CPU the contents of the CUNTX and CUNTZ are written in the memory MEM. With regard to one onward stroke werein the memorized contour return point and the contents of the CUNTX and CUNTZ become equal, the detection of the abrupt change point and the writing into the MEM are carried out.

摘要： PURPOSE:To ensure a smooth working of the machine mobile part, by converting the signal showing a large extent of shift of the variation component into the signal having a small variation component and then applying this signal to the servo system. CONSTITUTION:The signal (a) showing the extent of shift is supplied according to the clock (b). And in case n=4 is satisfied only for the memory element M1 at the time t1, 4 is written. In this case, other memory elements M2-M4 are 0, and accordingly the output of the adder circuit ADD becomes 4. And then this output is turned into 1/4 to change the output to 1. Both the contents of the element M1 as well as the input 4 are shifted to the M2 at the time t2, and as a result the addition output becomes 8 with the output of the circuit DV turned to 2. In the same way, the outputs 3 and 4 are obtained at the times t3 and t4. Accordingly, the input signal which varies from 0 to 4 can be converted into the output signal having the changing extent of 1/4. And the output varying by 0.5 is obtained at the times t18- t21. In such way, the input signal (a) is converted to obtain the output signal (c) having a small extent of change. As a result, a smooth shift can be secured for the machine mobile part.

摘要： PURPOSE:To effectively carry out copying work by sequentially changing a clamp level only when clamping feed is performed, performing copying work several times without performing it except when it is done. CONSTITUTION:The first and second memory means such as the counters for the positions A and B and a clamp level setting means such as the clamp level setting counter 11 are provided in the memory circuit 3. For control, copying is repeated, for example, between the position (point A) when clamping feed is first performed and that (point B) where clamping feed is not performed, changing the claming level. When no clamping feed is performed, copying is reset to the initial clamping level value and advances to the next area.
