This study presents the investigation on surface roughness and cutting speed using wire electric discharge machine for nickel based alloy (Inconel 600).Taguchi’s design of experiments methodology has been used for scheduling and designing the experimental array.Taguchi’s L-18 orthogonal array was selected and where in taper angle, peak current, pulse-on time, pulse-off time and dielectric flow rate has been considered as variable input parameters during machining. The result of the study reveals that among machining parameters it is preferably to go for increasing the value of peak current and pulse on time for better cutting speed but it is constrained when better surface finish is required. Larger value of taper angle increases cutting speed up to limited extent. The predicted optimal values for CS and SR are found to be 3.08 mm/min, 1.37 μm for single response optimization respectively. The confirmation experiments are also conducted and the values for CS and SR are found to be 3.06 mm/min and 1.29 μm for single response optimization respectively.
