An experimental investigation on effect of Al2O3 Nanofluids minimum quantity Lubrication (MQL) in CNC Machining of EN353.

The growing demands for high productivity of machining need use of high cutting velocity and feed rate. Such machining inherently produces high cutting temperature, which not only reduces tool life but also impairs the product quality. Application of cutting fluids changes the performance of machining operations because of their lubrication, cooling, and chip flushing functions. But the conventional cutting fluids are not that effective in such high production machining, particularly in continuous cutting of materials likes steels. So Nano fluids have novel properties that make them potentially useful in heat transfer medium in cutting zone And Minimum quantity lubrication (MQL) presents itself as a viable alternative for turning with respect to tool wear, heat dissipation, and machined surface quality. This study compares the mechanical performance of MQL Vegetable oil & MQL Nanoluids for the turning of EN353 based on experimental measurement of cutting temperature, cutting forces, surface finish, and dimensional deviations. This study prepares the effect of MQL and Nano fluids with 3% volume Al2O3 on the machinability characteristics of EN353 mainly with respect to Surface Roughness and Temperature dissipation. Experimental analysis for two different conditions –MQL oil and MQL + Al2O3 Nanoparticles was carried out.
