With the rapid development of material science and precision machining technology, high-precision optical components are playing an increasingly important role in optoelectronics, laser, aerospace, national defense and other fields. Precision machining is an effective way to solve the problem of high size precision, high surface quality and high shape precision, can greatly improve the processing efficiency of parts, special precision machining is a kind of widely used nonmechanical precision machining technology, precision machining technology research and development level has become one of the important basis of measuring the overall level of Chinas engineering industry. When the precision processing industry enters the era of tracking the final processing precision, it is difficult to achieve a qualitative breakthrough in improving the precision of processing equipment. In terms of the domestic production level, the accuracy of the blind tracking of the processing unit greatly increases the processing cost, but it may not necessarily achieve the satisfactory processing accuracy results. From this perspective, extensive monitoring studies on various factors affecting grinding accuracy. 【Keywords】optical products; precision machining; quality testing
