Abstract: In this work, process parameters are optimized in turning of EN25 steel with different types of coated carbide tools by the application of combined VlseKriterijumska Optimizacija I Kompromisno Resenje in Serbian (VIKOR) method. The selected process parameters are cutting speed, feed rate, depth of cut and types of coated tool for minimization of micro hardness, surface roughness and maximization of Material Removal Rate (MRR). VIKOR method uses VIKOR index values to obtain optimum combination of process parameters using suitable coated tool. The result revealed that this proposed method is appropriate for solving multi criteria optimization of process parameters. Also, results showed that cutting speed of 167 m/min, feed rate of 0.28 mm/rev and depth of cut of 1.8 mm are the optimum combination of process parameters.
