Machining is one of the important and most challenging jobs in manufacturing firms. There are various parameters related to machining processes such as the amount of material removed, life of the tool, surface quality of the machined product, wear rate of tool, coolants/lubricants used etc. One of the main concerns in any machining processes is the rise in temperature at the machining zones as it affects the workpiece properties as well as the performance of the cutting tool. This could be overcome by removal of the heat generated at the machining zone by using coolants/lubricants. It is clear from the earlier reported works that addition of nanoparticles to coolants/lubricants has proved better heat dissipation ability at the machining zone. This review lays emphasis on the prospects of nanoparticle added coolants/lubricants for various machining processes and the related challenges. In this paper an attempt is made to report an individual nanoparticle wise comprehensive review on some of the widely used coolants/lubricants used in machining zone suspended with nanoparticles of aluminum oxide, boric acid, copper, carbon nano tubes, diamond, graphite, molybdenum disulfide, silver, silica, titania and zinc oxide.
