Abstract: This work explains the optimization of milling variables of duplex stainless steel by employing Taguchi technique. The milling tests are carried out at three levels of feeds and spindle speeds. The average of results and ANOVA are employed to investigate the machining performances. The results exposed that the feed and spindle speed are the most important variables influencing the cutting force and surface finish. It is determined that, the spindle speed is the most important variable influencing the tool wear. Confirmation tests are conducted at optimum machining conditions in order to verify the predicted results and the error is within 5%.
Keywords: Duplex Stainless Steel, Milling Operation, Optimization, Taguchi Technique.
