ABSTRACT:
An automatic control for a grinding system is disclosed for controlling the advancement of a grinding wheel into a workpiece to provide a substantially constant time span between the termination of the operation of the feed means which advances the grinding wheel and the attainment of the final size of the workpiece for each workpiece machined. The control generates a reference time span and if the actual time span deviates by more than a preselected time period from the reference time span, the control develops a control signal adjusting the advancement of the grinding wheel during the grinding of the following workpiece.
