Title:

MACHINE TOOL AND CONTROL DEVICE FOR MACHINE TOOL

Document Type and Number:

WIPO Patent Application WO/2016/047485

Kind Code:

A1

Abstract:

Provided are a machine tool and a control device for the machine tool that enable the avoidance of a problem where a cutting tool cuts a workpiece beyond a predetermined cutting tool machining stop position. A machine tool (100) and a control device (C) for the machine tool are provided with an amplitude control means (C1) that controls the amplitude of reciprocal oscillation by an oscillation means. When a cutting tool (130) reaches a cutting tool machining stop position on a workpiece (W) in a machining feeding direction (Z axis direction), the amplitude control means (C1) reduces the amplitude of reciprocal oscillation by an oscillation means (160) in accordance with a feeding operation in the machining feeding direction. Due to this configuration, the problem where the cutting tool (130) cuts beyond the predetermined cutting tool machining stop position is avoided.
