PURPOSE:To facilitate correcting operation by recognizing the corrected value of a feed speed by a numeric controller. CONSTITUTION:The output of a counter 21 for speed correction and that of a register 22 for data storage are sent to a multiplier 23, whose product V is sent as a speed corrected value to another multiplier 2. In an initial state, the register 22 has a 1 (100%), and the output of the multiplier 23 is determined by the value of the counter 21. The counter 21 goes up or down corresponding to a switch D or (u), thus varying the speed corrected value. With a speed recognition switch T, the counter 21 is set to a 1 and the value of the multiplier 23 is set in the register 22, so the corrected value is set without varying the value of the multiplier 23. To make further correction, the value of the counter 21 is increased or decreased. |
