Paper Abstract

In the processing of large aspheric mirror, uniform removal means the process of equal removal at the whole surface in grinding and rough polishing stage. It aims to remove the subsurface damage layer at forming and grinding stage. It also smoothes the surface for reducing even eliminating mid-and-high-frequency error on the mirror. The combined processing method is using different diameter of laps by spatial frequency error model of reasonable matching in fabrication of workpiece. In this paper, the uniform removal method of combination NC manipulator and the Computer Controlled Active Lap is used. From the ring removal function model, the processing of combined uniform removal is simulated and analyzed. Compared with the CCAL uniform removal processing, it can get the much better uniform removal effect.
