INTRODUCTION The parameters like voltage, spark gap, capacitance The demand for miniature components are were considered and the output obtained was MRR. increasing every day. Micro EDM is a very The results shows that voltage is a major promising machining operation to meet the contributor for MRR whereas spark gap is a minor requirements in the production field due to the high contributor than capacitance.
