Abstract:
Provided is a machine tool that can be positioned at a tool replacement position that corresponds with a tip attachment state when a cutting tool held by a turret is positioned at the tool replacement position. This machine tool comprises: a workpiece-holding device that holds a workpiece and rotates about a main axis; a turret to which is attached a cutting tool on which a tip can be mounted and removed, the turret executing a process on the workpiece using the tip; a slide device that causes the turret to move in a sliding manner in each of a first direction parallel to the main axis and a second direction perpendicular to the first direction; a rotation device that rotates the turret; and a control unit. The control unit has: a determination unit that determines whether or not an end-of-service-life tip, which is a tip that needs to be replaced, is present among tips attached to the cutting tool held by the turret; and a position adjustment unit that, when the determination unit determines that an end-of-service-life tip is present, controls the slide device to position the end-of-service-life tip at a tool replacement position and adjusts the tool replacement position in accordance with the position on the turret where the end-of-service-life tip is held.
