Optimization of Cutting and Cutting Fluid Application Parameters in Turning of AISI 52100 Hardened Alloy Steel Under Minimal Cutting Fluid Application

Abstract

Hardened alloy steel materials are in great demand in automotive and allied manufacturing industries due to their better strength, wear resistance and high thermal stability. The hard turning offers many potential benefits over conventional grinding operations. During hard turning, the excessive heat generation and temperature affects the tool wear, tool life and surface integrity of the machined components. The cutting force and cutting temperature are the important technological parameter to control the machining process. The cutting fluid removes and reduces the heat from the cutting zone through cooling and lubrication action, but the use of conventional cutting fluid is being restricted due to the cost, health and environmental concern associated with its use in machining processes. The machining performance and cost-effectiveness can be improved by minimizing the cutting fluid. The main objective of this research work was to investigate the effect of cutting parameters and cutting fluid application parameters on cutting force and cutting temperature in turning of AISI 52100 hardened alloy steel with multilayer coated carbide insert under minimal cutting fluid application. The result showed that the minimal cutting fluid application (MCFA) technique significantly reduces the cutting force and cutting temperature compared to dry turning.
