Abstract

Siiij1e point diamond turning technique for optical crystals is reported in this paper. The main factors influencing the machined surface quality are discovered and the regularities of machining process are drawn. A new paraieter Rs is introduced to evaluate the surface quality of diamond turned optical crystals. Under the optiiized machining conditions, airror surface of roughness value Ra 0.006 jii is obtained on single crystal gerianiui.
