Experimental Investigation on Effect of Machining Parameters on Surface Roughness in Thermally Assisted Turning of Mild Steel

Abstract

Thermally Assisted machining(TAM) is used to decrease the cutting force in metal cutting process of hard to cut materials. Researches have been carried out to investigate reduction in cutting force. Surface roughness is important parameter and researches have been done to study effect of machining parameters on surface roughness for different machining processes.In this work, experiments were carried out to investigate effects of speed, feed, depth of cut and temperature on roughness in Thermally Assisted Turning (TAT) of mild steel. Optimum machining parameters were obtained by Taguchi method from the experimental results.
