Developing Environment Friendly Nanofluids for Minimum Quantity Lubrication in Machining Processes

Modern-day machining operation has become more economical, with increasing challenges towards efficient machining that is eco-friendly and safe to use. To make the machining process eco-friendly, a new method is introduced, i.e. the Minimum Quantity Lubrication (MQL). It has been successfully used as cutting fluid for near-dry applications because of its environmental friendliness. Formulation of cutting fluids is a subject of research where authors use oil as the base material for lubrication and to deal with the heat liberated during the process of machining. Since conventional cutting fluids may not offer better lubrication characteristics, solid lubricants are also been used as additives to reduce friction between the two surfaces sliding against and over each. The paper discusses the advantages of the eco-friendly fluid (with additives) as a cutting fluid in reducing the temperature and frictional forces at the tool/workpiece interface; ensuring enhanced performance of the machining.
