Definition
Diamond machining refers to cutting processes which yield ultraprecise surfaces, that is, surfaces with relative figure errors <10−5 and surface roughness Sa <10 nm using single crystal diamonds as cutting tools. These tolerances can only be achieved with ultraprecision machines and ultraprecise tools, and the term diamond machining is synonymous with ultraprecision cutting and ultraprecision machining.
Theory and Application
Diamond Tools
Ultraprecise cutting tools applied in ultraprecision machining have to meet extremely tight geometrical tolerances. Generally, a cutting edge waviness <100 nm and roundness rβ<50 nm are required for machining of optical quality surfaces. Moreover, tool life depends on wear resistance and chemical inertness with respect to the machined workpiece material. The only known tool material meeting all these requirements is monocrystalline diamond which can be ground and polished for generating sharp and...
