ABSTRACT:
A machine tool capable of automatically correcting an orientation of a workpiece or machining attachment based on detection results from position detectors that the machine tool inherently has. The machine tool comprises: position detectors; position deviation determining means; contact detection means that detects a contact between a probe and a surface of the workpiece or the machining attachment based on a position deviation; movable axis stopping means; coordinate value detection means; inclination determining means; and correction means. The inclination determining means moves linear axes to perform detection of contacts between the probe and the surface of the workpiece or the machining attachment at least two different points, and determines an inclination of the workpiece or the machining attachment using the obtained coordinate values. The correction means corrects a mounting error of the workpiece or the machining attachment, or corrects the machining program based on the determined inclination.
