Analysis of Nanofluid Enriched Minimum Quantity Lubrication on Machining of Bearing Steel

Abstract

newlineDuring the metal cutting process, heat-affected zone is generated at the cutting tool-workpiece newlineinterface. For the minimization of the heat affect zone, the cutting fluid is supplied at the newlinemachining zone in bulk quantity. The liters of cutting fluid consumed during the machining newlineprocess and leads to the generation of an unhealthy atmosphere on the shop floor in metal newlinecutting industries. These issues were resolved by implementing a minimum quantity lubrication newlinesystem on the machine tool. With the effective implementation of a minimum quantity newlinelubrication system, very less quantity of cutting fluid directed at machining zone to reduce the newlineeffect of generated heat. In the current research work, bearing steel turning process newlineperformance was evaluated on a CNC lathe machine tool under various cooling environments. The cutting fluids were supplied at the machining zone by using a minimum quantity newlinelubrication system. The dry, flood, vegetable oil, mono and hybrid nanofluids are the cooling newlineenvironments utilized during bearing steel turning operation. Castrol HYSOL MB 50 soluble newlineoil was utilized for flood cooling and in view of sustainability, biodegradable Max Mist newlinevegetable oil was utilized for minimum quantity lubrication cooling environment. For mono newlinetype of nanofluid, Al2O3, CuO and ZnO nanoparticles were synthesized using two-step method.
