AbstractThe EDM process is adequate for machining of narrow slots in low machinability materials, such as Ni based alloys used for aeronautical applications. This paper studies the influence of main process parameters involved in this process. The objective is to determine the effect of parameters related to the discharge process (current, pulse time and servo voltage) on machining time and electrode wear. Influence of discharge parameters has been studied using Central Composite Design of Experiments. Results reveal that discharge current as well as the time pulse, are the most influencing process parameters. Trends of material removal rate and electrode wear versus current, pulse-time and servo voltage have been analyzed
