PURPOSE:To attain the same feed control as the operation of a main machine by executing feed control for a synchronous feed command by generating a pulse equivalent to a pulse generated from a pulse coder from the inside of the titled device. CONSTITUTION:A control program is stored in a storage device 201 in an NC device 101 and a peripheral speed command value V or the like is calculated through an input control circuit 202 and a central processing part 203. A main axis control part 204 calculates a rotational frequency command value S to a main axis motor 104 by the command value V and a present position Xm from a position control circuit 207 and the number SP of rotational pulses commanded to a position detector 106 is calculated. A feed speed control part 205 finds out a feed speed (f) to a feed speed command value F and drives a driving part 102 and a motor 103 in a moving table through a pulse distributer 206 or the like. Thus, synchronizing operation is attained by the feed speed (f) based upon the speed command value F. |
