Definition

The term “ultraprecision cutting” refers to cutting processes which yield ultraprecise surfaces, that is, surfaces with relative figure errors <10−5 and surface roughness Sa <10 nm. These tolerances can only be achieved with  ultraprecision machines and ultraprecise tools. Since single crystal diamonds are commonly used as cutting tools, ultraprecision cutting is often called “diamond 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 r β<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 flawless...
