PURPOSE:To attain manually the oblique cutting, arc cutting and other processes as well as the discontinuation of tool operations, by securing the shift of a tool also with a feed speed pulse given from a manual pulse generating means. CONSTITUTION:A tool 3 is stopped at a place near a point (a) and a changeover switch 19 is changed to the manual operation mode. Under such conditions, a manual switch 20 of a manual pulse generator 17 is changed to a coupled feed mode and a handle is turned for output of a feed speed pulse HP. This pulse HP is supplied to a microcomputer 10 and also to an axis control unit 12 in the form of a feed speed pulse FP2 via a switch circuit 18. As a result, the minimum unit position is set to an interpolator of the unit 12 from the computer 10 for each output of the pulse HP. Then the feed pulses are supplied to each axis drive unit 13 from the unit 12 in response to the pulse FP2. thus the tool 3 is shifted by the minimum unit amount. |
