Performance Evaluation of Nanographite-Based Cutting Fluid in Machining Process

Health and environmental concern on use of cutting fluids during manufacturing has led to development of minimum quantity lubrication (MQL) which requires specialized fluids having superior properties. In the present work, a new nanofluid is prepared and is evaluated for lubricating property. Its performance is evaluated in machining process by applying it as MQL in turning by measuring cutting forces, cutting temperature, flank wear, roughness of machined surface, and examining chip morphology. Newly prepared nanofluid showed improvement in the lubricating properties of base fluid and also showed superior performance compared to dry machining, flood cooling, and MQL application of conventional cutting fluid.
