Abstract: Spring steel (EN47) samples are machined (turning) using Sandvik make coated tungsten carbide tool insert with different nose radii (0.4 and 0.8mm) in dry condition and the results are compared with each other. Spring steel is widely used in the manufacturing of vehicle components such as crankshaft, knuckle and leaf spring. EN47 spring steel material is relatively low cost compare to other alloy steels. Experiments are conducted based on taguchi L9 technique. Input parameters are cutting speed, feed rate and depth of cut. The corresponding output parameters are cutting force, surface roughness and tool tip temperature have been analyzed. Experimental result reveals that better surface roughness obtained with higher nose radius. ANOVA results confirm that cutting force is influenced by depth of cut (ap), surface roughness is influenced by feed rate (f) and tooltip temperature is influenced by cutting speed (Vc). Chip morphology and machined surface samples are analyzed using scanning electron microscope (SEM). � 2018 Elsevier Ltd.
