Abstract Experiments were performed using conductive powder-mixed dielectric in electrical discharge machining of Super Co 605 and optimization is carried out by means of Taguchi method. The process input parameters selected are flushing pressure, discharge voltage, pulse on-time, polarity, peak current, and pulse off-time to study the performance characteristics in the form of surface roughness, tool wear, and material removal rate. Experiments based on appropriate orthogonal array are conducted and significant parameters are identified. The optimum process conditions simultaneously leading to a better surface roughness, lower tool wear, and higher material removal rate are then demonstrated by confirmation testing. The experimental results confirm an improvement in surface roughness, tool wear, and material removal rate when Taguchi method is used.
