Abstract

The objective of the current work is to optimize the end milling process machining parameters in end milling of EN 31 steel. Surface Roughness (SR), Dimensional Deviation (DD) and Material Removal Rate (MRR) are some of the crucial findings in this work. In this work, the weights are calculated by using numerical tool AHP (Analytic Hierarchy Process) method, and VIKOR(Vise Kriterijumska Optimizacija Kompromisno Resenje) and WASPAS (Weighted Aggregated Sum Product Assessment) methods are used in analyzing optimum machining parameters. These techniques are utilized for multi-objective optimization which minimizes SR, DD and maximizes the MRR. Results showed the effectiveness of VIKOR approach as well as WASPAS method, both methods are appropriate to any metal cutting operations on superior with multi-number of objectives concurrently.
