Metal cutting operations generate the heat and forces due to the friction and energy lost in deforming the work piece. There are the several types of cutting fluids. The disadvantages of mineral based straight oils and soluble oils are poor heat dissipating properties and increase fire risk. On other hand the synthetic fluids no contain petroleum or mineral oil and based on alkaline organic and inorganic compounds. It reduce heat and very less environmental and health hazards. The objective of this work is to analysis the experimental results upon using the different types of Nano metal powder such as molybdenum disulphide (MoS2), graphite, Nano boric acids (NBA) in synthetic based cutting fluids as glycerin and compared to dry machining with respect to cutting temperature and surface qualities. According to the “solid heat transfer enhancement theory” the thermal conductivity of liquids and heat transfer capacity increased by adding the solid Nano particles in it. Compared study on the effect of NBA on Nano graphite fluid and Nano MoS2 fluids with glycerin base fluid, the temperature and surface roughness were analyzed and shown the result that average temperature is reduce by Nano MoS2 with NBA. This is lower than Nano graphite addition with NBA by 15.26% to 17% and from dry condition 24% to 40%. With compared study, result show that the molybdenum disulphide MoS2 nanoparticles based glycerin with Nano boric acid gives more efficient for cutting process as compared to dry machining and other used cutting fluids.
