Wire Electrical Discharge Machining (WEDM) is a non-traditional thermo-electric process capable of machining hard materials of highly complex three dimensional shapes. In this paper, the dry WEDM experimentation is conducted using oxygen as a dielectric medium. The deionized water is replaced by the oxygen as a dielectric medium to ameliorate the environmental impact in the machining surroundin...

Background: Wire Electrical discharge machining (WEDM) has higher capability for cutting complex shapes with high precision for very hard materials without using high cost of cutting tools. During the WEDM process, the wire behaves like a metal string, straightened by two axial pulling forces and deformed laterally by a sum of forces from the discharge process. Major forces acting on the wire c...
