The studies of an experimental investigation evaluate the effects of EDM machining parameters such as MRR, EWR with two different electrode materials. The process parameters such as Input current, Pulse on time and duty cycle keeping flushing pressure constant. With the use of Design of Experiment The full factorial design of experiment (L2)4 is used to study the effects of machining parameters on die steel material. Investigations selected the machine Model Electra plus leader-1-znc Electra machine, through practical, investigation the output parameters of EDM increases with the increase in input current and the best machining rates are achieved with copper electrodes, better surface roughness compare to brass electrode. A brass electrode with higher input current and maximum pulse on time resulted in more EWR compared to copper electrodes.
