Abstract
A machine tool a tool includes a supporting member relatively movable to a workpiece along a predetermined axis, a servo motor configured to drive the tool supporting member to the workpiece along the predetermined axis, a sizing sensor configured to measure a profile of the workpiece and to output a size deviation of measured values from a target profile, and a position detector configured to detect at least one of a relative position of the tool supporting member to the workpiece and a rotational position angle of the servo motor. The a servo driver is configured to drive the servo motor, and has a first feedback control having an output based on the size deviation, and a second feedback control based on an output of the position detector. The servo drives the servo motor by combining the outputs of the first and second feedback controls.
