Introduction Increased demands for precision components made of brittle materials such as optical glasses and advanced ceramics are such that conventional grinding and polishing techniques can no longer meet the requirements of today’s precision engineering.
Diamond cutting is a promising alternative to grinding and polishing techniques for fabricating high quality surfaces on brittle materials as a well-defined single point tool is more predictable than a multi-point grinding wheel [1-3].

The materials may be from organic materials or made materials.
During the process of polymeric materials degradation, oxygen diffusion occurs prevalently in the unstructured regions.
Furthermore, some research is needed on the economy, performance, and efficiency of materials built from face masks’ waste.
