Abstract

The methodology of Modified Taguchi optimization method for simultaneous minimization and maximization of Surface roughness (Ra), machining time and material removal rate of EN31 affect the aesthetical aspect of the final product and hence it is essential to select the best combination values of the CNC drilling process parameters to minimize as well as maximize the responses. The experiments were carried out by a CNC lathe, using physical vapour deposition coated (TiAlN, CrAlN) & un-coated HSS drilling tool insert for the machining of EN31.

                The experiments were carried out as per L27 orthogonal array with each experiment performed under different conditions of such as speed, type of drilling tool, and feed rate. The Taugchi method and analysis of variance (ANOVA) was employed by using MINITAB-16 software to identify the level of importance of the machining parameters on Surface roughness (Ra), Machining time and Material Removal Rate (MRR).
