Electric Discharge Machining (EDM) PPT

3. Electric discharge machining (EDM), sometimes colloquially also referred to as spark machining, spark eroding, burning, die sinking or wire erosion, is a manufacturing process whereby a desired shape is obtained using electrical discharges (sparks).

Research on Electrical Discharge Machining of ...

surface damage caused by the Electrical Discharge Grinding (EDG) process and its optimization strategies. In addition to the graphitization and residual stress, several issues that assumed to be thermal damage indications caused by the process are highlighted. These include the formation of porous surfaces, cutting edge undercuts
