MACHINE TOOL AND CONTROL DEVICE FOR MACHINE TOOL

Document Type and Number:

WIPO Patent Application WO/2016/056526

Kind Code:

A1

Abstract:

　The purpose of the present invention is to provide a machine tool with which entanglement of long, continuous shavings about a workpiece and/or a cutting tool is avoided, and damage to the machined surfaces of the workpiece is avoided, during a thread-cutting process being performed on the workpiece; and a control device for the machine tool. Provided are: a machining device (100) equipped with an oscillation setting means (C1) by which a workpiece (W) and a cutting tool (130) are advanced relative to one another in the machining direction while undergoing relative rotation, and are relatively oscillated in reciprocating fashion in a diametrical direction of the workpiece and subjected to a process of cutting spiral shapes multiple times in order to perform a thread-cutting process, the pattern of oscillation during each cutting process accompanied by reciprocating oscillation being set such that a section cut during a prescribed cutting process partially includes a section that has already been cut in a different cutting process; and a control device (C) for the same.
