Ionic liquids assisted LQL for turning PH steels: smart methodology

ABSTRACT

17-4 precipitation hardening stainless steel is a recognized material with good strength and can overcome abrasion and corrosion resistance, which is frequently preferred in the situation of extreme pressure and high pressure. However, it is a tough-to-cut material due to its high ductility. Hence, it is necessary to obtain the optimal parameters for improving the machining performance of the 17-4 PH steel. In this research, the significance of the surfaces machined is analyzed with cutting temperature along with flank wear by changing turning input factors such as cutting speed, feed and machining conditions (dry, oil and ionic liquid (IL)) with low-quantity lubrication. The optimal solution was determined using response surface method. The outcomes reveal that environment outperforms other control parameters. IL is found to be an important factor in determining the responses.
