摘要 | A fast ultrasonic grinding for SiC off-axis large aspheres used in space remote sensors was researched. The principle of grinding, the selection of diamond grinding wheel bond, the selection of machine tool, and setting grinding parameters were analyzed, and the grinding process was designed. A high precise model of off-axis aspheric surfaces was established on the basis of the principle of reverse engineering, and the online testing method in fine grinding state for a large off-axis aspheric mirror by a laser tracker was established. Combination with an engineering example, the model of a large SiC off-axis asphere with the aperture of 700 mm700 mm was established by the reverse engineering principle, and it was grinded by ultrasonic method and measured by the laser tracker. After 3 cycles (4 hours per cycle of grinding), the PV value (45.986 m) and RMS value (7.949 m) of the surface error are reduced to 12.181 m and 2.131 m, respectively. As compared with three coordinate testing results, the errors of PV value and RMS value are 0.8923 m and 0.3128 m, respectively. It concludes that the grinding technology realizes fast and high precise grinding for the SiC off-axis large asphere and improves its machining precision, efficiency, and surface quality. , 2015, Chinese Academy of Sciences.
