A workhead, for the grinding of non-circular workpieces, equipped with a pair of compensating cams to shift the workpiece axis relative to the axis of the grinding wheel. The "X" cam shifts the workpiece axis horizontally; the "Y" cam shifts it vertically. The rotation of work and cams is synchronized so that the line jointing the point of grind, the center of the grinding wheel and the instant center of curvature of the desired surface is coincident with the feed and compensation line of the grinder at all times. |
