EDM (Electric Discharge Machining)machine was used for machining of conducting cutting materials such as steel 304in dielectric solution (diesel fuel) by supplied byDC current values (10, 20, 30, 42 and 50A). Voltage of (140V) was used to cut (1) mm thickness.
The experimental results reveal that the material removal rate enhanced by increasing the current values also show that the Electrode wear ratio rises with increase in the current values. It is also concluded that the material removal rate reduces with increasing the pulse off time values and the electrode wear ratio.
