EN47 spring steel samples are machined using coated tungsten carbide tools of different nose radii and the results are compared with each other. Cutting parameters are considered using one factor at a time (OFAT) approach. Input parameters are cutting speed (Vc), feed rate (f) and depth of cut (ap) varies from 256 rpm to 572 rpm, 0.043 mm/rev to 0.117 mm/rev and 0.25 mm to 0.75mm respectively. The corresponding output performance are cutting force, surface roughness and tool tip temperature have been analyzed. The result reveals that the lower cutting force and better surface roughness obtained with 1.2 mm nose radius similarly for minimum tool tip temperature obtained with 0.8 mm nose radius.
