COMPARISON OF MAIN EFFECT OF VEGETABLE OIL AND AL2O3 NANOFLUIDS USED WITH MQL ON SURFACE ROUGHNESS AND TEMPERATURE

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 Nanofluids 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. In this study Vegetable oil with MQL is compared with Al2O3 Nanfluids and MQL for the turning of EN353 steel based on experimental measurement of surface roughness and temperature. This study prepares the effect of MQL and Nano fluids with 3% volume Al2O3 on the machinability characteristics of EN353 steel mainly with respect to surface roughness and temperature dissipation. Experimental analysis for two different conditions ? MQL + Vegetable Oil and MQL + Al2O3 Nanofluids were carried out.
