Title:
MACHINE TOOL CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/062607
Kind Code:
A1
Abstract:
Provided is a feature with which it is possible to precisely achieve a desired surface roughness even if a cutting tool is replaced after the start of processing or if the shape of a blade edge of the cutting tool has changed, to improve the readability of a processing program, and to reduce the time and effort required in creating the processing program. Specifically, provided is a control device 1 for a machine tool that processes a workpiece W while moving the workpiece W relative to a cutting tool T, the machine tool control device 1 comprising: a surface roughness acquisition unit 11 that acquires, from a processing program, a target surface roughness set for a workpiece W being processed; a tool surface roughness information acquisition unit 12 that acquires tool surface roughness information relating to the surface roughness of the cutting tool T; and a feeding amount control unit 14 that, on the basis of the tool surface roughness information, determines feeding amount information relating to a feeding amount per relative rotation of the cutting tool T and the workpiece W such that the surface roughness of the workpiece W reaches the target surface roughness.
