Optimization of milling parameters of ASTM a 995 grade 4a duplex stainless steel using taguchi technique

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%.
