Title:
MACHINE TOOL CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/241552
Kind Code:
A1
Abstract:
Provided is a machine tool control device that can realize a desired scrap length while suppressing deterioration in machining accuracy. This control device 1 is for a machine tool which performs machining while causing a tool and a workpiece to oscillate relative to each other, the control device 1 being provided with: an oscillation command generation unit 13 for generating an oscillation command on the basis of an oscillation condition; an oscillation command correction unit 14 for correcting the oscillation command so that main-axis phases in given oscillation phases are not identical to each other; and a position/speed control unit 18 for causing the tool and the workpiece to oscillate relative to each other on the basis of a superposition command generated by superposing the oscillation command corrected by the oscillation command correction unit 14 on a movement command.
