Aspherical surface polishing with a ring polisher.
The ring-shaped polisher analyzed by Vinokur is modified to be a high-speed polisher for aspherical surfaces. The mathematical modeling of the ring polisher has been reformulated to examine the uniformity of surface polishing over the workpiece. The fabrication of a ring polisher is described, and experimental results of direct polishing of ground aspherical surfaces are discussed.
