Abstract
A grinding machine includes: a workhead () that rotatably supports a solid cylindrical or hollow cylindrical workpiece (W); a grinding wheel () that moves relative to the workhead () in a direction that intersects with a rotation axis of the workhead () to grind an outer peripheral surface of the workpiece (W); a measuring apparatus () that measures a position of an outer peripheral surface of the workpiece (W) corresponding to a rotation angle of the workhead (); an outer peripheral surface shape calculation unit () that calculates an outer peripheral surface shape of the workpiece (W) on the basis of the position of the outer peripheral surface of the workpiece (W) measured by the measuring apparatus () during grinding; and a grinding condition determination unit () that determines a condition of grinding, which is performed after measurement by the measuring apparatus (), on the basis of the calculated outer peripheral surface shape of the workpiece (W).
