Wire Electrical Discharge Grinding

INTRODUCTION WEDG (wire electro discharge grinding) technique is a special version of the micro WEDM method that was introduced firstly by Masuzawa et al. (1985) The WEDG process is considered as a finishing process where the purpose is to obtain good surface quality In WEDG no mechanical contact nor cutting is necessary for surface finish.

Difference Between EDM and EDG

Difference Between EDM and EDG

2020-10-28 · Electro Discharge Grinding (EDG) A form electrode made of electrically conductive metal is used as cathode. So spark is generated between the form electrode and the conductive workpiece. A wheel made of electrically conductive material acts as cathode. No separate electrode is used. Thus spark is generated between the wheel and workpiece.

However, there are numerous examples where electrical discharge machining is not the right solutions. EDM is a high precision machining method. EDM is a rather slow method compared to traditional machining. High-volume tasks are therefore not suited for this method. At the same time, the electro thermal process requires high power consumption.

Electrical Discharge Machining (EDM) is a non traditional machining and electro thermal process in which material from the workpiece is removed by using electrical discharges (sparks). It was first observed in 1770 by Joseph Priestley. He was an English physicist. In EDM machine the material is removed by rapidly recurring (repeating) discharges of current in between the electrodes.
