Document Type and Number:
WIPO Patent Application WO/2022/004546
Kind Code:
A1
Abstract:
Provided are a control device and a control method for a machine tool which are capable of further reducing a command-waiting time. This control device for a machine tool which controls synchronized operation of a main shaft and a feed shaft comprises: a numerical value control unit which creates a main shaft command and a feed shaft command on the basis of a tapping program; a main shaft control unit which controls the rotation operation of the main shaft in accordance with the main shaft command; a rotation detection unit which detects the rotation position of the main shaft; and a feed shaft control unit which controls, on the basis of the rotation position, the feeding operation of the feed shaft in accordance with the feed shaft command. The numerical value control unit has a main shaft command output unit which, when a cutting operation and pulling-out operation are carried out from a machining start position to a target position an arbitrary number of times, acquires from the tapping program the rotation amount and the maximum rotation speed of the main shaft in the cutting operation and pulling-out operation and which supplies the rotation amount and the maximum rotation speed of the main shaft to the main shaft control unit as the main shaft command.
