Abstract
Nowadays, solid lubricants are being considered as sustainable alternate
to the conventional cutting fluids. Solid lubricants such as graphite, molybdenum
disulfide, and boric acid etc. play vital role to achieve sustainability, productivity,
and surface quality in machining. This article presents an introduction to solid
lubricants and lubrication technique, highlights the use of solid lubricants in the
machining of difficult-to-machine materials, and reviews some previous articles
focused on solid lubricant based machining. The article aims to facilitate the
researchers working in the field to conduct further research and development.
