Electric discharge machining (EDM) is one of thermo-electric, non-conventional machining process. By EDM process can be machining of hard conductive materials which is complicated to machine by traditional machining, complicated shapes, with micro or macro removal rate. Each cutting process was controlled by several parameters, from that’s a voltages values. The aim of this work was study the effect of changing these values on material removal rate (MRR) of AISI 444 stainless steel. The EDM parameters were used in this study are voltage (140, 240) V, current I p (12, 24, 50) A, pulse on time T on (100, 200, 400) μs, and pulse off time T off (3, 6.5, 12) μs. For the design of experiments, the full factorial was used to analysis the result on Minilab 19 software. The results show the (MRR) was increasing with increasing in voltage. Maximum (MRR) that be achieved is (144.2308) mm 3 /min at higher value of voltage, current and pulse on time.
