Patent ID: 8287329

Claim:
A grinding machine comprising: a workhead that rotatably supports a solid cylindrical or hollow cylindrical workpiece; 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; a measuring apparatus that measures a position of the outer peripheral surface of the workpiece corresponding to a rotation angle of the workhead; an outer peripheral surface shape calculation unit programmed to calculate an outer peripheral surface shape of the workpiece on the basis of the position of the outer peripheral surface of the workpiece 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, wherein the outer peripheral surface shape of the workpiece includes at least any one of an outer peripheral surface shape of the workpiece with respect to a rotation center of the workpiece, an out of roundness of the workpiece and a surface texture of the workpiece.
