Powder mixed EDM (PMEDM) has emerged as one of the advanced techniques in the direction of theenhancement of the capabilities of EDM. Its use is particularly intense when very complex shapes on hard and brittlematerial with high geometrical and dimensional accuracy are required with increase of machining rate. In this work, theeffect of Silicon Dioxide (SiO2) powder mixing into the dielectric fluid of EDM on machining characteristics of EN-8 hasbeen studied with three input parameters Peak current, pulse on time and concentration of powder. The processperformance is measured in terms of Material Removal Rate (MRR) on weigh basis. The result outcome will identify theimportant parameters and their effect on MRR and SR of En-8 in the presence of SiO2 in a kerosene dielectric of EDM.Analysis shows that the percentage contribution of peak current peak current and pulse on time have higher percentagecontribution toward MRR. The experimental result analysis shows that the setting of peak current at high level (17 A),pulse on time at medium level (50 µs) and powder concentration at 6 g/lit produced highest MRR.
