Machining represents a thermo-mechanical reaction based on factors such as plasticity, wear and friction. The experimental design consists of conducting a series of turning trials on a titanium alloy Ti6Al4V using combinations of cutting parameters namely spindle speed (n) of 770 rpm; feed rate (f) of 0.2 and 0.4 mm/rev; and depth of cut (d) of 1 and 2 mm. The length of cut (L) of 10 mm remains constant for all trials. All trails are done under dry conditions. In this paper, a detailed investigation has been carried out to study the temperature at shear zone and the effect of cutting variables on temperature has been evaluated. The temperature in shear zone for each trial was measured using an infrared thermal camera.
