Kind Code:
A1
Abstract:
Provided is a machine tool with which a delivery position for delivering a workpiece to a partner device is set on the basis of a measurement result, while achieving a simplified device structure. This machine tool comprises: a contact detection device; a robot that has a holding member and holds a workpiece with the holding member and conveys the workpiece; a partner device that accepts the workpiece from the robot; and a control device. The contact detection device outputs, to the control device, a contact detection signal corresponding to a contact. The control device executes: a reference position setting process that involves controlling the robot and causing the contact detection device to come into contact with the partner device, acquiring, from the contact detection device, a contact detection signal when the contact with the partner device is detected, and setting the position of the robot at the time of contact as a reference position on the basis of the acquisition of the contact detection signal; and a position setting process that involves acquiring the length of the workpiece as an input value and setting a delivery position that is the position of the robot when the workpiece of the input value length is delivered from the robot to the partner device, on the basis of the acquired input value and the reference position.
