Study on High-Precision Computer-Controlled Aspheric Surface Processing Techniques

Abstract:

In this paper, two processing techniques—full parameters technique and part parameters technique—for aspheric surface grinding are expatiated. Both of them are based on the priciple of computer-controlled optical surface (CCOS) and developed from trajectory forming method. We also have carried out appropriative software to digitalize processing technology. Proved by practical process, both of them are reliable and reproducible. Full parameters technique is easy to operate, but the accuracy of surface is to large extent dependent on the accuracy of measurement; Part parameters technique can avoid these measurements, however, it has certain requirements for operator. However, its requirements are still much less than those of traditional technique.
