| 摘要: |
| 计算机控制光学表面技术（Computer Controlled Optical Surfacing,CCOS）是加工离轴非球面的一项重要技术。小磨头抛光的边缘效应严重制约CCOS技术的加工精度和加工效率。在获得影响边缘效应的关键参数后，结合残余误差等高线的路径规划，对CCOS产生的边缘效应产生的翘边现象进行修正；通过对一块体育场形离轴非球面的加工，获得了全口径光学测量数据，为后续精加工提供面形基础。 |

| Abstract: |
| CCOS (Computer Controlled Optical Surfacing) is an important technology for off-axis aspheric surface processing. Edge effect of small tool manufacturing restricts the machining precision and efficiency of CCOS technology. After the key parameters of edge effect were obtained, the warping edge effect of CCOS combined with the residual error trace contour path planning was corrected. The full aperture optical measurement data of a stadium off-axis aspheric is achieved by processing, which provides the fundament for subsequent finishing. |
