— Electrical Discharge Machining (commonly known as “EDM”) is an unconventional machining methodwhich is typically used for difficult to cut materials. In this process, the material removal takes place electro thermally bya series of consecutive discrete discharges between electrode and the work piece separated by a small gap which isdipped in a dielectric fluid. The spark is generated between tool and workpiece by the controlled pulsing of directcurrent. The present work has been under taken to study the effect of increase in pulsed current on material removalrate, electrode wear rate, and surface quality in alloy steels viz., EN 31, EN 8, HCHCr.The electrode materials viz.copper, brass, chromium copper are used to machine the alloy steels. Finally the main focus is find out best electrodematerial in order to achieve more efficient Material Removal Rate (MRR) coupled with reduction in Tool Wear Rate(TWR) and improved surface quality.
