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.
