Computer Numerical Control Turning on AISI410 with Single and Nano Multilayered Coated Carbide Tools under Dry Conditions

Martensitic stainless steels (AISI410) have excellent, such as, corrosion resistance, high strength, low thermal conductivity, and high ductility. On account of these properties, AISI410 is widely used in the manufacture of components in aerospace industries, turbine and compressor components, and nuclear applications. CNC turning of AISI410 is an important task in the manufacturing of components. Turning parameters such as cutting speed, feed rate, depth of the cut, and the cutting tool, play a major role in getting a good surface finish, while turning AISI410. In this article, carbide tools coated with multilayered TiCN+Al 2 O 3 , multilayered Ti (C, N, B), single layered (Ti, Al) N, and nano multilayered B-Tic are used for the turning study on AISI410, under dry conditions. Different cutting parameters, namely, cutting speed, feed rate, and depth of the cut are used for the optimal setting of the parameters on turning AISI410. Experiments were carried out using the Taguchi's L 27 orthogonal array. The effect of cutting parameters on surface roughness (SR) was evaluated and optimal setting conditions were determined for minimization of SR. Analysis of variance (ANOVA) was used for identifying the significant parameters affecting the response.
