Abstract
A controller uses detection information of a contact sensor or time-series data of a detection value related to a drive motor included in a rotation mechanism and/or a feed mechanism to acquire a coordinate value when a cutting tool comes into contact with a to-be-cut object or a component. The controller determines a relative positional relationship between the cutting tool and a rotation center of the to-be-cut object based on coordinate values when the cutting tool comes into contact with the to-be-cut object subjected to turning work or a reference surface whose relative positional relationship with the rotation center of the to-be-cut object is known at least at two positions different from a rotation angle position of the cutting tool during the turning work.
