The present invention relates to a system for measuring a grinding force between a workpiece and a grinding wheel during the operation of a computer controlled grinding machine. A force transducer is mounted on a drive screw assembly between a moveable slide and a motor used to control movement of the slide. The force transducer generates a control signal that is conditioned and received by a digital signal processor, which instructs a machine controller to perform grinding operations in response to the measured force.
