Abstract
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.
