Abstract: Martensitic stainless steels (AISI410) are widely used in engineering applications. AISI 410 has good mechanical properties because of high chromium content and high carbon content. A surface property such as surface roughness (SR) is critical to the function-ability of machined components. AISI410 are generally regarded as more difficult to machine material and results in poor surface finish. Optimized machining parameters are very important for controlling the required surface quality. In this paper, SR is analyzed produced by CNC turning on AISI410 with different cases of coated cutting tool under dry conditions. Multilayered coated with TiCN+Al2O3 of 14 µm insert is used for case-I, multilayered coated with Ti(C, N, B) of 6 µm insert is used for case-II and single layered coated with (Ti, Al) N of 3 µm insert is used for case-III. Experiments were carried out by using Taguchi’s L27 orthogonal array. The effect of machining parameters on SR is evaluated and optimum cutting conditions for minimizing the SR was determined. Analysis of variance (ANOVA) was used for identifying the significant parameters affecting the response. The obtained results are validated by confirmation experiments.
