Abstract

Space optical elements require highly surface shape precision and surface quality. Bonnet polishing, with new polishing tool and special motion trait, is a high precision and efficient optical component machining method, especially for aspheric surface machining. It has a extensive application prospect. Principle and developing process of related bonnet polishing technology are analyzed, and research situation and test result of bonnet polishing technology are introduced. Current situation of several important and critical technologies is reviewed. The removing characteristics material, control algorithm of resident time, control of marginal precision and latest-developed spray polishing technology are introduced significantly.
