In the practical fabrication  edge effect is an important problem which restricts the fabrication efficiency and accuracy seriously. In this paper  the edge effect is solved by working out the edge removal function and compensate with dwell time function. Skin Model is used to describe the pressure distribution when the tool hangs over the work-piece. The calculation model of edge removal function is derived from Skin Model theoretically. A removal function experiment is completed. The difference between the theoretical model and the experiment results is less than 5%. It means that the calculation model is suit for the practical fabrication. Than the dwell time is solved with edge effect compensation by matrix-based algorithm. In the end  actual experiment was done to validate the edge effect compensation method. 2010 Copyright SPIE - The International Society for Optical Engineering.   Optical Surfacing of Reflecting SiC Mirrors Of 520mm R-C System 会议论文  OAI收割 Xian, China, 2005-11-2 作者:  Lvjun Yuan;  Bin Wang 收藏  |  浏览/下载：33/0  |  提交时间：2013/12/28 SiC reflector  Optical surfacing of aspheric mirrors   Novel resistance iterative algorithm for CCOS (EI CONFERENCE) 会议论文  OAI收割 Current Developments in Lens Design and Optical Engineering VII, August 14, 2006 - August 15, 2006, San Diego, CA, United states 作者:  Zhang X.;  Zhang X.;  Zhang X. 收藏  |  浏览/下载：71/0  |  提交时间：2013/03/25 CCOS (Computer Control Optical Surfacing) technology is widely used for making aspheric mirrors. For most manufacturers  dwell time algorithm is usually employed to determine the route and dwell time of the small tools to converge the errors. In this article  a novel damp iterative algorithm is proposed. We chose revolutions of the small tool instead of dwell time to determine fabrication stratagem. By using resistance iterative algorithm  we can solve these revolutions. Several mirrors have been manufactured by this method  all of them have fulfilled the demand of the designers  a 1m aspheric mirror was finished within 3 months.
