(BQ) In this study, the effect of machining parameters of EDM process including on-time, current, voltage, the engaging
time between workpiece and electrode, and pre-EDM roughing on electrode wear were experimentally investigated. Main effects of factors and interactions were considered in this paper and regression equation was derived. A L50 (21 × 511) Taguchi’s standard orthogonal array was employed as experimental design. Copper was used as electrode to machine the hot work tool steel 1.2714, which is widely used to make forging dies and mandrels.
