ABSTRACT:
A workpiece W and a grinding wheel G are relatively moved in Z and X-axis directions perpendicular to each other, the rotational axis of the grinding wheel is inclined relative to the X-axis, and the grinding wheel is composed of a taper section Ga having a generating line parallel to the Z-axis and a spherical section Gb connecting with the generating line at the maximum diameter portion of the taper section Ga. While performing a cam profile generating motion, the grinding wheel is controlled to perform a plunge grinding feed toward the workpiece in the X-axis direction to effect a plunge grinding on the cam of the workpiece and then, while performing the cam profile generating motion, is controlled to perform a traverse grinding feed in the Z-axis direction to effect a traverse grinding on the cam.
