Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges (sparks). Lecture 20: Die-Sinker EDM and Wire Cut Electric Discharge Machining (WEDM) 4.1 ( 11 ) Lecture Details. 60. 0000011784 00000 n Taguchi orthogonal array was used for planning the experiments to optimize the control variables for better surface roughness while machining AISI 420 modified metallic material. Input like wire length and wire quantity provided by pressing push button also the real time data can read on 16 X 2 LCD. In addition to the X-Y table travels, wire EDM’s have U / V travels for providing the movement to cut tapers. Wire EDM is also useful for making punch tools.
