Germanium lenses are widely used in various scientific and technological applications mainly infrared optical components. The performance of these lenses depends upon the surface finish, which is challenging to achieve during ductile-regime machining. It is crucial to provide the optimum parameters to ensure the high-quality surface, without surface and subsurface damage. In the present work, an attempt has been made to analyse the effect of input machining parameters on surface finish and subsurface damage distribution, induced during the diamond turning. Taguchi's optimization has been performed to optimize the parameters affecting the performance and surface quality of fabricated components. Abbott-Firestone (A-F) curve is utilized to study the distribution of peaks and valleys on the machined surface. Additionally, chip morphology and machining forces are analysed to study the material removal behaviour at varying parameters. Further, indentations are performed on the best and worst combinations to examine the effect of parameters selection on surface cracks propagation. It is found that surface with a greater number of valleys leads to chipping during indentation. In this study, a surface roughness of 2.3 nm is achieved with minimum subsurface deformation.

“…The authors studied and compared surfaces that differed in microgeometry but had the same roughness. The Abbott-Firestone curve [22][23][24][25] and R k parameter have become widely used to evaluate the relationship between machine parts' performance properties and surface roughness. Peculiarities of estimating the surface condition using the Abbott-Firestone curve were described in [26,27].…”

Causes of the in-service damage to hydrocylinder liners were investigated, and the requirements to their working surfaces were systematized. Roughness parameter Ra was found not to provide a precise estimate of the surface quality because its reduction did not affect surface microgeometry. Additionally, the surface quality was assessed by the Abbott-Firestone curve during the finishing operation. The optimized manufacturing technology for obtaining hydrocylinder liners was offered based on having the required microgeometry and surface quality provided by cutting operations. The quality and service characteristics of internal surfaces of hydrocylinder liners were improved by changing technological operations. In particular, the semi-finish turning was chosen to provide for the surface roughness parameter Ra within 6.3–8.0 μm and the roughness pitch parameter S within 0.4–0.6 mm and homogeneous surface structure. The finishing rolling was replaced by burnishing to form a regular microrelief.

“…So the optical performance is highly dependent on the surface quality and the degree of surface/subsurface damage. Manufacturing steps of optical component, from grinding to polishing, are known to be major contributors to the generation of such mechanical defects [5]. During grinding step, although diamond wheel grinding has used widely, some surface/subsurface damages generated during grinding are difficult to remove in a subsequent polishing operation.…”
