Keywords: GRA Material removal rate Surface integrity Taguchi WEDM Wire wear ratio a b s t r a c t This paper presents the investigation on surface integrity, material removal rate and wire wear ratio of Nimonic 80A using WEDM process. Taguchi's design of experiments methodology has been used for planning and designing the experiments. All of the input parameters and two factors interactions have been found to be statically significant for their effects on the response of interest. SEM was
