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

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 0.05 (mm/rev)- depth cut 0.1(mm)-cutting speed 80(m/min) 0.15(mm/rev)-depth 0.3(mm)-cutting 200(m/min) has been used in hard turning D2 steel. It was determined that 0.3% ZrO 2 wt% observed to be machinability compared dry Minimum Quantity Lubrication (MQL) environment. Finally, sustainability assessment through Pugh Matrix Assessment (PMA) presented potential nanofluid-MQL for improvement hardened steel cleaner production.
