WIPO Patent Application WO/2012/172833

A1

Provided is a machine tool that is capable of easily measuring a workpiece in a short period of time and processing the workpiece with high precision. For this purpose, the machine tool, which processes a workpiece (W) with a tool (T) by moving a principal axis (14) on which the tool (T) can be mounted and the workpiece (W) relative to each other horizontally and vertically, is provided with: a saddle (12) that rotatably supports the principal axis (14) and is supported to be movable vertically; a workpiece-measuring instrument (30) that contactlessly measures the workpiece (W); a transport device (15) that is provided on the side surface of the saddle (12) and transports the workpiece-measuring instrument (30) between a measurement position (P1) and a standby position (P2); and an NC device (20) that, after assessing whether or not the workpiece (W) has a poor fitting or poor shape based on the measurement results of the workpiece-measuring instrument (30), controls the movement of the tool (T) and the workpiece (W) according to the assessment results.
