Effect of discharge current and electrode size on material removal rate and wear ratio in electrical discharge machining

In the present study the effect of electrode size and discharge current on material removal rate (MRR) and wear ratio (WR) during electrical discharge machining has been investigated. The work and electrode materials were mild steel and copper respectively. The diameters of the cylindrical electrode...
