	The removal function of edge effect and amending with dwell time function (EI CONFERENCE) 会议论文 OAI收割 5th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Advanced Optical Manufacturing Technologies, April 26, 2010 - April 29, 2010, Dalian, China 作者: Luo X.; Zhang F.; Zhang F.; Wang X.-K.; Zheng L.-G. 收藏 \| 浏览/下载：35/0 \| 提交时间：2013/03/25 Computer Controlled Optical Surfacing (CCOS) is widely used for making optical aspheric mirrors. 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.
	Novel method for optimizing polishing tool-path in CCOS based on weighted-iterative algorithm (EI CONFERENCE) 会议论文 OAI收割 4th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Advanced Optical Manufacturing Technologies, November 19, 2008 - November 21, 2008, Chengdu, China 作者: Zhang X.-J.; Wang X.; Wang X.; Wang X.; Wang X.-K. 收藏 \| 浏览/下载：41/0 \| 提交时间：2013/03/25 In Computer Controlled Optical Surfacing (CCOS) polishing tool-path is the base of solving other control parameters such as dwell time. In order to improve the fabrication results of polishing off-axis aspheric a novel method to optimize the tool-path is discussed in this paper. The optimizing method named weighted-iterative algorithm is according to the balance principle of the particle system. The power factor of each dwell point represents the requirement of dwell density. Considering the factors which influence the polishing result the power factors cosist of three elements include constant error distribution and dwell distance of workpiece edge. The tool-path is solved by numerical iterative method. In the end an error data is simulated with actual parameters using the matrix-based algorithm with two different tool-paths. The one is X-Y uniform spacing model and the other one is to optimize it based on the first. The comparison shows that the results of the optimized one are much better than traditional one especially the rms convergence rate. Theory of the algorithm is simple and exercisable and it satisfies practical requirement as well. 2009 SPIE.
	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：63/0 \| 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.
