Provided is a machine tool with which the accuracy of a stop position of a drive subject can be improved in a case where semi-closed loop control is performed. The machine tool includes a guide mechanism for guiding at least one drive subject among the tool and the workpiece, a servo motor that moves the drive subject guided by the guide mechanism, and a control unit that performs semi-closed loop control on the servo motor so as to move the drive subject from an initial position to a target position. The control unit performs the semi-closed loop control so as to apply to movement of the drive subject a vibration component with which, from a midway position between the initial position and the target position to the target position, an advancing motion toward the target position and a retreating motion opposite to the advancing motion are performed repeatedly.

Provided is a machine tool with which a load acting on a drive system for driving a drive subject when the drive subject starts to move toward a target position can be reduced. The machine tool includes a guide mechanism for guiding at least one drive subject from among a tool and a workpiece, a servo motor that moves the drive subject guided by the guide mechanism, and a control unit that controls the servo motor so as to move the drive subject from an initial position to the target position. The control unit controls the servo motor so as to apply vibration in which an advancing motion toward the target position and a retreating motion opposite to the advancing motion are performed repeatedly to the drive subject for a set period up to a point at which the drive subject starts to move toward the target position from the initial position.
