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.

Machinability and surface roughness are poor in turning AISI410, because of low thermal conductivity, high ductility, high strength, and rate of work hardening. Coated carbides are basically a cemented carbide insert coated with one or more thinly layers of wear resistant materials. It is well known that coating can improve the SR. This chapter presents the optimum cutting parameters for dry CNC turning on AISI410 by different types of coated cutting tools using Taguchi technique. The cutting tools were used multilayered TiCN + Al2O3, and nano multilayered B-TiC. Experiments were carried out by using Taguchi’s L27 orthogonal array. The effect of cutting parameters on SR was evaluated and optimum cutting conditions for minimizing the SR was determined. Analysis of variance (ANOVA) was used for identifying the significant parameters affecting the responses.

Surface quality is one of the most specified customer requirements in machining products. Surface quality of roughness is critical to the functional ability of machined components. Austenitic stainless steels (AISI 316) are generally regarded as more difficult to machine material due to their high strength, ductility and high work hardening tendency. Surface roughness (SR) is a vital role requirement in determining the surface quality of the product. The minimisation of SR is essential for the achievement of high quality. In this paper is to analyse the SR produced by CNC turning process on AISI 316 by different cases of coated cutting tool used at dry conditions. Multi-layered coated with TiCN+Al 2 O 3 for first case and single-layered coated with (Ti, Al)N for second case. Experiments were carried out by using Taguchi's L27 orthogonal array. The effect of cutting parameters on SR was evaluated and optimum cutting conditions for minimising the SR was determined. Analysis of variance (ANOVA) was used for identifying the significant parameters affecting the responses.
