Abstract

The spacing between an abrasive type surface polishing tool and the surface of the work piece that is being polished is controlled dynamically so that variations in the area of the abrasive pad in contact with the surface of the work piece compensated, thereby eliminating size variations in this contact area and the accompanying variations in material removal that produce surface height fluctuations.
