Duplex stainless steel materials are widely used in various industrial sectors due to its excellent stress corrosion cracking resistance and higher strength levels. The present work presents the results of experimental investigation carried out in end milling operation of cast nitrogen alloyed duplex stainless steel ASTM A 995 Grade 5A. The end milling operations were carried out with coated carbide cutting tool inserts. The experiments were conducted at three different spindle speeds, three different feed rates, and three different axial depth of cuts. The cutting parameters are optimized using Taguchi method. The effects of cutting speed, feed rate, and depth of cut on the surface roughness were analyzed using mean and analysis of variance. It is found out that the significant variable affecting the surface roughness is the feed rate, then the spindle speed, and the axial depth of cut.
