This paper is concerned with selection of optimal superfinishing conditions. During superfinishing of cylindrical surfaces, an axially oscillating abrasive stone is pressed against the rotating workpiece. Experimental results are presented which show the effect of contact pressure, process kinematics, and grit size on superfinishing behavior. An optimal contact pressure is found at which the removal rate is maximized. The ration of the axial oscillation frequency to the workpiece rotational frequency should be selected so as to avoid integer values, which result in low stock removal, and half values, which can lead to lobe formation. Finer grit stones provide smoother surface finishes but less stock removal. Therefore the grit size selected should be only fine enough to generate the required surface roughness.
