Abstract: Cutting fluids of various types are usually employed to control the heat generated in machining. The continued application of conventional cutting fluids is being challenged by the need to reduce overall volume of fluids, minimize health risks. Functions such as improving tool life and machining process efficiency, enhancing surface integrity are obtained by using cutting fluids. While the effect of formulated cutting fluids on surface roughness and tool wear in machining SS202 with coated carbide were investigated and compared with conventional oil-in-nanoparticles emulsion cutting fluid. Mineral, synthetic and semi-synthetic cutting fluids involve in the ecological cycle with air, soil and water and their toxicity effect damages the ecosystem. By study of various research papers we concluded that to overcome problems in machining, vegetable based cutting fluids can be used to optimize machining conditions but we choose coconut oil due to its thermal and oxidative stability which is higher than that of other vegetable based cutting fluids. We used coconut oil while machining of stainlesssteel 202 material with coated carbide tool and analysis of material and tool.
