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.
