Abstract
According to an embodiment of the present invention, a torque variation of a servomotor, which is measured in a numerical control apparatus of an existing numerical control machine tool, is observed, and a backlash is detected by calculating a transfer distance of an output shaft of the servomotor at a torque peak, without adding additional positioning detection equipment, thereby detecting an accurate backlash amount without adding additional equipment.
