Classification: CPC B  G | IPC B  G

Claim 1:
2. A cutting apparatus comprising:
a rotation that rotates a spindle to which a cutting tool or to-be-cut object is attached;
a feed drive motor that moves the cutting tool relative to the to-be-cut object; and
a controller that is programmed to control rotation of the spindle by the rotation drive motor and relative movement of the cutting tool by the feed drive motor, wherein
the controller is programmed to control a capability of using detection information of a contact sensor or time-series data of a detection value related to the rotation drive motor and/or the feed drive motor to acquire a coordinate value when a cutting edge of the cutting tool comes into contact with the to-be-cut object, and
the controller is programmed to specify, based on coordinate values when the cutting tool is moved relative to the to-be-cut object subjected to cutting work by a feed capability of the feed drive motor in a movement direction not used for the cutting work to bring a cutting edge of the cutting tool into contact with the to-be-cut object at least at two positions, at least one of an attachment error of the cutting tool, an error in shape of the cutting edge of the cutting tool, and a deviation in the movement direction of the cutting tool relative to the to-be-cut object.
