Modern manufacturers worldwide look for the cheapest quality-manufactured machinedcomponents to compete in the market. Good surface quality is desired for the properfunctioning of the parts produced. The surface quality is influenced by the cutting speed,feed rate, depth of cut, and many other parameters. In this paper, the Taguchi method – apowerful tool to design optimisation for quality – is used to find the optimal machiningparameters for the turning operation. An orthogonal array, the signal-to-noise (S/N) ratio,and the analysis of variance (ANOVA) are employed to investigate the machiningcharacteristics of super duplex stainless steel bars using uncoated carbide cutting tools.The effect of machining parameters on surface roughness was discovered. Confirmationtests were conducted at optimal conditions to compare the experimental results with thepredicted values.
