Experimental Study of the Critical Process Parameters of Machining of Stainless Steels Using the Taguchi Approach
High strength, high ductility and low thermal conductivity cause the austenitic stainless steels to be hard materials to machine so that heat concentrates at the tool cutting edge due to their properties. This study aims to optimize turning parameters of AISA 304 stainless steel. Turning tests have been performed in three different feed rates (0.2, 0.3, 0.4 mm/rev) at the cutting speeds of 120, 160 and 200 m/min. An analysis of variance (ANOVA) has been made to determine the effects of each parameter on the tool wear and the surface roughness using the Taguchi approach. It is being inferred that cutting speed has the main influence on the flank wear and as it increases to 200 m/min, the flank wear decreases. The feed rate has the most important influence on the surface roughness and as it decreases, the surface roughness decreases as well.
