Abstract
A machine tool, which carries out machining on a workpiece using a tool, is equipped with a servo motor configured to cause axial movement of the tool, an imaging device configured to capture an image of the tool at a specified imaging magnification, a display unit configured to display the image captured by the imaging device, a command position calculating unit configured to, in the case that the imaging magnification is changed, calculate a movement command position of the tool on the basis of the imaging magnification before and after having been changed, so as to maintain a relative positional relationship between a specified point of the tool in the image, and an imaging center position in the image before and after the change in the imaging magnification, and a motor control unit configured to control the servo motor on the basis of the movement command position.
