Environmental sustainability during machining of hardened steel using nanofluid: A case study

Abstract

The positive effects of nanofluid-assisted minimum quantity lubrication include improved performance during machining and environmental sustainability. In the present study two cutting parameters levels such as feed rate of 0.05 (mm/rev)- depth of cut of 0.1(mm)-cutting speed of 80(m/min) and feed rate of 0.15(mm/rev)-depth of cut of 0.3(mm)-cutting speed of 200(m/min) has been used in the hard turning of D2 steel. It was determined that the 0.3% ZrO2 wt% observed to be improved machinability as compared to dry and Minimum Quantity Lubrication (MQL) environment. Finally, the sustainability assessment through the Pugh Matrix Assessment (PMA) presented the potential of nanofluid-MQL for improvement of machinability of hardened D2 steel for cleaner production.
