ABSTRACT
Metal cutting is a subtractive manufacturing process used to give size, shape, and surface finish to the finished components. Metal cutting is a high-shear, high energy-consuming, and heat-generation process with a considerable amount of tool wear. It is important to reduce the cutting force and improve the metal removal rate to increase productivity and to produce quality products meeting customer specifications. Cutting fluids can reduce the cutting force, reduce heat generation and improve surface finish. Wet machining gives a better surface finish than dry machining but at the expense of extra cost. Minimum quality lubrication (MQL) is an impressive alternative to conventional dry machining processes. Rather than spraying 194lubricants as jets, MQL small amount of coolant or mist of coolant is sprayed at the cutting zone. This causes a significant reduction in cutting forces, cutting temperature, and material wear by reducing the friction coefficient significantly. This chapter deals with nano-additives assisted MQL and optimization of the process parameter to minimize the cost and maximize the beneficial decision variables such as MRR, etc. The experimental procedure is discussed in detail. The importance of the various nanoparticles in MQL is discussed in the synthesis procedure. Finally, Detailed optimization of the nano-assisted MQL procedure is presented for effective cutting processes.
