Abstract

The Computer-Controlled Optical Surfacing (CCOS) technology is widely used for making aspheric mirrors, because of its high accuracy, simple process conditions, low cost and other merits. The characteristic of the removal function of a polishing tool is a fundamental factor in determining convergence rate in CCOS process. The ideal removal function in CCOS shows a Gaussian-like character which has the maximum removal at the center and gradually reduces to zero with the radius increasing. In this paper, we present a novel approach to get an ideal removal function by tri-rotors machinery. According to the Preston equation and time-sharing synthesis, we established mathematical models in the modes of trirotors movement. Through the simulation based on the emulated material removal function, we get the polishing process technological parameter. Then the experimental setup and results are given. The practical process proves that the result is basically equal to the simulation result, which validates the feasibility of this simulation optimization method and has a certain degree of guiding to practical process.
