Thermal and Tool Wear Studies On Mild Steel Turning

Abstract

The present works involves the study of thermal and wear behaviour of tool and work interface. Experiments were conducted on a Turn master 35 automatic lathe. Various cutting forces, temperature at tool tip, thickness and weight of chips formed during machining along with the tool wear data were recorded. The influence of cutting parameters was studied. Based on the experimental data plots are obtained. Finite element analysis was done using ANSYS software tool and was used to find the tool tip deflection, counterplots. Thermal analysis was done to determine the temperature distribution over machining interface. Good agreement was found between the predicted and measured cutting forces.The analysis provides new insight into the chip formation and temparature distribution over tool tip and work interface in mild steel turning.As turning of mild steel rod using HSS is one among the major machining operations in manufacturing industry and tool wear results obtained would significantly contribute to the cutting parameters optimization during manufacturing of some of the parts for automobile and other structural related sectors.
