NC milling is the mainly forming processing method of aspheric surface of brittle material. In the study of the NCmilling aspheric surface processing technology,surfaceshape error directly affects the machining accuracy and production efficiency. According to the principle of NCmilling aspheric surface, milled silicon aspherical lens by Satisloh GI3P precision milling machining center, the factors affecting silicon aspherical lens surfaceshape error were analyzed, and the method of fixed compensation surface shape error was discussed. The results show that the main factors influencing the aspherical surface shape accuracy are offset error of z axis,offset error of the origin of the CNC program and rotation axis of the actual workpiece ,and error of grinding wheel wear. By correcting error, machining precision and machining efficiency of the aspherical shape are effectively improved.
