Abstract
In a grinding machine, a retraction grinding is performed after a first advance grinding. Within a rotational range for a cylindrical workpiece to rotate from a present rotational phase to a target rotational phase in the retraction grinding, target grinding resistances in respective rotational phases are generated based on residual grinding amounts in the respective rotational phases of the cylindrical workpiece. Then, the retraction grinding is performed and controlled to make a grinding resistance detected by a force sensor agree with the target grinding resistances in respective rotational phases.
