Effect of discharge current and electrode size on material removal rate and wear ratio in electrical discharge machining / Ahsan Ali Khan, Mohammad Yeakub Ali and Md. Mohafizul Haque

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 electrod...

Central stations 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 electrodes were 9, 15, 20 and 30 mm. Experiments were conducted for three current values of 2.5, 3.5, and 6.5 A. MRR and WR were analyzed with respect to current density.
