MACHINE TOOL CONTROL DEVICE

WIPO Patent Application WO/2021/153483

A1

The objective of the present invention is to provide a machine tool control device with which chips can be reliably divided and discharged, and with which damage to a tool can be suppressed by reducing shock when the tool cuts into a workpiece. A machine tool control device 100 which controls a main shaft that causes a tool T to rotate relative to a workpiece W, and which executes a cutting process by controlling a feed shaft to move the tool T and the workpiece W while causing the same to oscillate relative to one another in a feed direction, is provided with an oscillation command generating unit 16 which generates an oscillation command on the basis of a predetermined oscillation condition, and a position and speed control unit 15 which controls a motor 30 that drives the feed shaft, on the basis of a superimposed command generated by superimposing the oscillation command generated by the oscillation command generating unit 16 onto a position command or a position deviation, wherein the oscillation command generating unit 16 changes at least one of an oscillation command phase progression method and an oscillation command amplitude, on the basis of either an oscillation phase calculated on the basis of the predetermined oscillation condition, or time.
