An apparatus for use on a grinding machine for adaptively controlling the grinding process. The grinding process is initiated by a coarse-feed motion of a grinding tool into a workpiece. A gaging device is adapted to the workpiece and produces a gaging signal representing the excess material remaining thereon. A feed back circuit produces a control signal as a function of the power required by the grinding process, and the control signal represents an amount of material capable of being removed from the workpiece by the measured power. A comparator circuit is responsive to the gaging signal and the control signal and produces an output signal when the excess material remaining on the workpiece equals the amount of material capable of being removed by the measured power. The output signal is operative to terminate the coarse feed, and the remaining material is removed primarily as the result of the force which has built up between the tool and the workpiece as indicated by the measured power. When the gaging signal indicates the part is ground to size, the tool is retracted from the workpiece.
