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.
