An overview on performance of metal working fluids with enrichment of nanoparticles for machining process

Tool wear is natural phenomenon, and this leads to tool failure which is caused mainly due to various aspects like the surface of the work piece, material of the work piece to be machined and other. The application of the metal working fluids (MWF's) (or generally coolant) is considered to reduce the friction between the work and tool and to provide lubrication as well as cooling. In a machining process, the use of coolant is essential to dissipate the heat generated and to enhance various properties like productivity, tool life, machinability, etc. There are many types of oil based MWF's are available like mineral oil, semi-synthetic oil, synthetic oil based MWF's. But lately vegetable oil based MWF's are being used because of its eco-friendly nature. Recently Nanoparticles are used to enhance the properties of metal working fluids. In this paper there is brief explanation on preparation of metal working fluids with enrichment of Nanoparticles.
