ABSTRACT:
A mechanism for programming the number of increments of feed of a grinding wheel into a workpiece and the extent of the feed of each increment. The mechanism has a cam and a follower operably associated with a grinding wheel to feed the wheel toward a workpiece in response to rotation of the cam. A motor drives the cam and a dial in synchronization with the cam which has a plurality of dogs thereon which actuate limit switches to stop the motor and hence the feeding of the wheel into the workpiece. The number of increments in which the wheel is fed into the workpiece is a function of the number of dogs placed on the dial and the extent of the feed of each increment is a function of the angular position of the dogs on the dial.
