Abrasive Electrical Discharge Grinding
Abrasive Electrical Discharge Grinding (AEDG) Introducing mechanical effects into EDG process leads to increase in metal removal rate. For example, in the case of Al-SiC composite, removal rate of the AEDG process ( t e = 10 m s, and n = 500 rpm) is about 5 times greater than that of EDM process, and about twice of EDG process.
All About EDM Machining (Electrical Discharge Machining)
The History of Electrical Discharge Machining The history of EDM Machining Techniques goes as far back as the 1770s when it was discovered by an English Scientist. However, Electrical Discharge Machining was not fully taken advantage of until 1943 when Russian scientists learned how the erosive effects of the technique could be controlled and used for machining purposes.
