Abstract

Abstract: Variation of temperature during turning is the major cause of tool wear and that is one of the responsible factor for reducing tool life due to excessive tool wear. Presented work is an experimental investigation of heat flux and heat transfer coefficient due to increasing temperature cause of variation of cutting speed feed rate and depth of cut, all experiments are performed based on the design of experiment followed by response surface methodology and mathematical relations are established in between dependent and independent variables. Experimental work is performed in dry conditions by selecting Aluminium alloy (7068) as a work piece with Titanium Nitride coated carbide tool bits. The comparison results show high agreement between the physical cutting experiments with an analytical model that are also drawn with the help of MATLAB (simulink). The aim of presented work is to develop mathematical model of generated temperature on tool work interface at different input parameters during machining of turning operation. Utility of the whole study is beneficial for an aerodynamic in which the application of this alloy plays a vital role.
