ABSTRACT:
A method of grinding an arcuate (concave or convex) surface of a workpiece in a grinding machine involves rotation of the workpiece about an axis which may but need not intersect the workpiece and which need not include the center of curvature of the arcuate surface. The locus of material-removing contact between the working surface of the griding wheel and the arcuate surface of the workpiece is maintained on a straight line which connects the center of the grinding wheel with the center of curvature of the arcuate surface. The grinding wheel and the workpiece further perform translatory movements in directions at right angles to each other. If the arcuate surface is inclined with reference to such directions, the workpiece or the grinding wheel is moved in a third direction transversely of the directions of translatory movement of the workpiece and the grinding wheel.
