Abstract:
1. A control apparatus of a machine tool configured to be operated in a manual pulse mode where an NC program is executed in response to a pulse signal generated by a manual pulse generator according to a rotation of a handwheel and in a single block mode where the NC program is executed and stopped for every block of the program, the control apparatus comprising: a block stop detecting section that detects whether the execution of the NC program is stopped at an end of a block when both the manual pulse mode and the single block mode are selected; a rotation detecting section that detects whether the rotation of the handwheel is stopped and then restarted after the execution of the NC program is detected to be stopped at the end of the block; and a control section that controls an operation of the machine tool such that the execution of the NC program is restarted from a next block in both the manual pulse mode and the single block mode when the rotation of the handwheel is detected to be stopped and then restarted.
