“…Kiyak [10] investigated the effect of variable factors namely pulse times, wire feed speed, pulse pause times and work piece thicknesses on material removal rate, hardness and surface roughness of machined work piece during wire EDM on tool steel. Saini et al revealed the optimum values of trepan drilling in ceramic composites with solid state pulsed Nd:YAG laser using traditional and artificial intelligence techniques [11][12][13][14][15]. Machining on crankshaft conducted with confirmatory optimum values of design parameters.…”

Better toughness, abrasion resistance and machining characteristics make tool steel suitable material for dies and tools. Electrical discharge drilling is thermal energy based spark machining process. In this process metal removes from the work along circumference of hole to be cut is due to spark phenomena. In present study circular cutting on steel is performed with wire electric discharge machine using design of experiment approach. Four design variables pulse on & off time, wire feed and current have taken while material removal rate considered as quality parameters. Total nine experiments conducted on work material using orthogonal array. Taguchi technique is used to identify the significant process parameter on quality parameter.
