Abstract
The numerical controller controls a machine tool and performs rigid tapping on a cutting surface of a workpiece. The numerical controller determines, based on a first allowable synchronization error between a rotation of a spindle and movement of each axis of a workpiece coordinate system and an inclination angle of a cutting surface, a second allowable synchronization error between a spindle and a feed axis and monitors a synchronization error between the spindle and the feed axis based on a second allowable synchronization error that has been determined.
