ABSTRACT:
A cam grinding machine rotates a workpiece by using a servomotor which is capable of being rotated at a variable speed. A memory device stores data of rotational speeds of the workpiece corresponding to angular positions thereof in order to maintain the circumferential speed of the workpiece constant. A detecting device detects an angular position of the workpiece. A counter is responsive to the detecting device and reads out rotational speed data stored in the memory device in order to apply the same to the servomotor.
