What is Electrical Discharge Machining (EDM) Process and ...

Apr 12, 2017 · 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.

Electro-Discharge Machining (EDM) | Industrial Engineering

In electro-discharge machining (EDM) process, the control of erosion of the metal is achieved by the rapidly recurring spark discharges produced between two electrodes, one tool and the other work, and spark impinging against the surface to the workpiece which must be an electrically conducting body.

Difference Between EDM and ECM – Electro-Discharge ...

Electro-Discharge Machining (EDM) is one thermal energy based process where material is removed by localized melting and vaporization. Intense heat is generated by means of electric sparks. Here the tool made of conductive material is made one electrode (negative polarity), while the conductive workpiece is made another electrode (positive polarity); and a small gap is maintained between the two.
