PURPOSE:To perform tool offset control, by storing the amount of offset of the tool having >=N of tool number, by means of the storage of the amount of offset and the tool number to an offset memory. CONSTITUTION:When a shift command is given, an operation processing section 104 operates incremental values DELTAXa, DELTAYa, DELTAZa of axes and input the result to a pulse distributor 107. The pulse distributor 107 executes the operation of pulse distribution based on the incremental values DELTAXa, DELTAYa, and DELTAZa, outputs distribution pulses XP, YP and ZP, which are inputted to servo circuits 108X, 108Y and 108Z to shift the tool along the command path. Further, the section 104 reads out the tool length offset amount from the storage area of the offset memory 106 corresponding to the tool number next to the alphabet H, correct the incremental value Z and gives outputs to the pulse distributor 107. |
