Finite-Element Simulation of Electrical Discharge Machining (EDM) Process


I. INTRODUCTION
Electric discharge machining (EDM), sometimes
colloquially also referred to as spark machining, spark
eroding, burning, die sinking or wire erosion, is a
manufacturing process whereby a desired shape is obtained
using electrical discharges (sparks). Material is removed
from the workpiece by a series of rapidly recurring current
discharges between two electrodes, se ....etc
