摘　　要：大型非球面主镜能动磨盘加工(CCAL)是有别于传统加工和数控加工(CCOS)的新型加工工艺。通过对能动磨盘结构的研究,建立了工件的能动磨盘磨削模型,分析了加工中的边缘效应,并采用压强补偿的方法对磨削模型进行了优化。在Φ1300mm(F/2)非球面主镜能动磨盘加工实验中,以该优化的模型仿真的主镜加工面形与经Hartmann-Shack传感仪检测的实际面形基本吻合。Computer Controlling Active Lap （CCAL） manufacture is a new manufactunng technology compared with the traditional manufacture and Computer Controlling Optical Surface （CCOS） for large aspheric mirrors. The removal function model of active lap is found based on the investigation of active lap structure and working features. After analyzing the edge effect, we optimize the founded model through the method of pressure compensation. The mirror surface predicated by the optimized model above basically matches the mirror surface tested by Hartmann-Shack wavefront sensor during the experiments of Φ1300mm （F/2） aspheric mirror manufactured by active lap.
