Abstract

This research investigates the cutting zone temperature while machining Titanium alloy (Ti-6Al-4 V), as Ti64 happens to be the most important material utilized in building aircraft, dental implants and jet engines. This alloy is the low thermal conductivity material which develops high temperature build up in material during machining. The elevated cutting zone temperature affects surface integrity and tool life of the material. These are mainly influenced by machining parameters for instance, feed rate (f), depth of cut (d) and cutting speed (v). Thermal images depicting the temperature build up zone were captured using thermal imaging camera during machining. Experimental investigations reveals that the cutting temperature has increasing trend with cutting speed. The machining model was done based on experimental outputs using Response Surface Methodology (RSM) technique. The response of the developed model was mapped within the range of the cutting conditions. The optimal combination of machining parameters was evaluated to minimize temperature. PVD carbide tool and CVD coated tools performance are almost similar. CVD coated tools produces short chips during machining whereas PVD coated tool produces comparatively long chips.
