Abstract: Today's growing demand for steels and spring steels are widely used in industries as they possess high yield strength and their property resistance to deform easily. Spring steels have huge demand in many large scale industries, because of their applications in nuclear power plant, jet engine parts, forming tools and extrusion dies. EN47 is one of such spring steels with relatively low cost. Machinability study of EN47 material was analysed using a L27 orthogonal array (OA) for dry turning condition using TiCN/Al2O3/TiN CVD coated tungsten carbide insert with nose radius of 0.4mm. Depth of cut (d), Speed (v), feed (f) and are varied to the level-3. During machining, cutting forces and cutting temperatures was measured using Kistler based dynamometer and heat gun respectively. Surface roughness was measured by using Mitutoyo SJ201 after machining. Machined surface and chip were analysed using scanning electron microscope (SEM). Tool tip temperature, surface finish and cutting forces are optimized using Design of Experiments technique and proof trails are conducted with satisfactory results. � 2017 Elsevier Ltd.
