| Abstract: | This paper is concerned with the selection of optimal superfinishing conditions. During superfinishing of cylindrical surfaces, an axially oscillating abrasive stone is pressed against a rotating workpiece. Experimental results are presented that 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 ratio of axial oscillation frequency to 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. |
