Abstract
The single-point diamond turning (SPDT) procedure can provide the desired surface polish of optical components as well as form accuracy. The diamond tool used in the SPDT method for achieving sub-nanometer surface polish has desirable qualities such as nanometric edge sharpness and wear resistance. Infrared (IR) optics is one of the fastest developing disciplines of traditional optics. Infrared (IR) applications in optics necessitate strong surface integrity and nanometric roughness free of microfractures, scratches, and microcracks. This work intends to provide an overview of the ultra-precision SPDT approach for achieving sub-nanometer surface polish on IR materials. Following that, the elements that govern the formation of surfaces are described and analysed in detail using some notable work in this subject. This paper further presents the impact of input machining parameters on the distribution of the cutting temperature and thermo-mechanical deformation of the diamond tool while machining IR materials.
