PURPOSE:To guarantee a trial processing with high accuracy, by controlling feed in a speed proportional to a generated pulse speed from a manual pulse generator and controlling the path of a tool with NC command even if the mode is changed over to the manual pulse generator. CONSTITUTION:A pulse train outputted from manual pulse generators Px, Py and Pz is outputted to an interpolating device 5 via a computer CPU and further to a position control circuit 6 at the next state. The position control circuit 6 outputs a speed command voltage to a speed control unit 7. The speed control unit 7 controls the speed of feed motors Mx, My and Mz of each axis with a speed feedback signal Sf from a speed detector 8a. As a feeding command of each axis (path of tool), data on a tape 1 or from a memory 4 are used, and the feed speed is varied in accordance with the speed of pulse train generated by rotating a handle of the manual pulse generators Px, Py and Pz. |
