ABSTRACT:
A conditioner grinder having a workpiece carried by a car that reciprocates adjacent a grinding wheel. The grinding wheel is supported for movement in a direction both normal to the surface to be ground and transversely across the surface to be ground. Movement of the grinding wheel in both of these directiond is through conventional hydraulic actuators. The hydraulic actuator indexing the grinding wheel transversely across the workpiece contains a pair of pressure sensors that measure the differential pressure across the piston of the actuator. The differential pressure signal is subtracted from a position error indicative of the difference between the actual position of the grinding wheel and the desired transverse position of the grinding wheel. In the event that the position error exceeds a predetermined value, a pressure command added to the position error increases or decreases linearly with time toward the position error, thereby providing a steady-state error signal to cancel the signal resulting from a differential pressure across the piston under steady-state conditions.
