Study of the Surface Integrity of AISI 4140 Steel in Wire Electrical Discharge Machining

he Wire Electro Discharge Machining (WEDM) process is a violent thermal process where literally thousands of electrical discharges are produced in a fraction of a second in order to erode a certain volume of metal. The process is most used in situations where intricate complex shapes need to...
