Experimental Investigation of Surface Roughness and Power Consumption in Turning Operation of EN 31 Alloy Steel

The paper presents an experimental study of power consumption and roughness characteristics of surface generated in turning operation of EN-31 alloy steel with TiN+Al2O3+TiCN coated tungsten carbide tool under different cutting parameters. The study shows the influences of three cutting parameters like spindle speed, depth of cut and feed rate affecting surface roughness as well as power consumption while turning operation of EN-31 alloy steel. The experimental setup includes five different spindle speed keeping feed rate of 0.08 mm/rev and depth of cut of 0.4 mm constant, five different feed rate keeping spindle speed of 710 rpm and depth of cut of 0.4 mm constant and five different depth of cut keeping feed rate of 0.08 mm/rev and spindle speed of 710 rpm constant. The experiments were conducted to investigate the effectiveness of surface roughness and power consumption in turning operation of EN 31 alloy steel.
