Abstract
A servo motor is driven to rotate a feed axis to move a movable part of a machine tool controlled by a numerical controller in a feed axis direction. A sensor that senses force from the outside (worker) applied to the movable part and a direction of the force is provided on the movable part. The numerical controller generates a movement command for moving the movable part in the direction of the force detected by the sensor and drives the servo motor based on the movement command.
