Abstract

The current research emphasizes on the impacts on different machinability aspects of AISI 4340 hardened alloy steel using copper oxide, aluminium oxide, zinc oxide and iron oxide based nanofluids as cutting fluid while performing turning operation using uncoated cermet cutting insert. A detailed comparative analysis was done in order to determine which nanofluid performed effectively. The minimum quantity lubrication (MQL) technique was used which sprayed the cutting fluid in the form of mist at the cutting zone. In the MQL technique a single fluid was used which served both the purpose of a coolant and lubricant and did so in minimum quantity. The turning operation was performed on the workpiece by using four different levels of cutting speed, feed and depth of cut. Due to the enhanced thermophysical properties of the nanofluid better dissipation of heat generated due to the friction generated between the tool and the workpiece was observed. The use of nanofluids resulted in enhanced tool life and superior surface quality.
