ECM is the inverse of electroplating. The workpiece is the anode, and the tool is the cathode. A high-current (1000-10000 A), low-voltage (5-25 V) DC source pumps an electrolyte (NaNO3 or NaCl) through the gap. According to Faraday’s 2nd Law, workpiece atoms ionize and are swept away. Since material removal occurs at the atomic level (no heat, no force), ECM produces a bright, stress-free finish. It is the standard process for rifling gun barrels and machining large turbine hubs.

The hardness of the workpiece doesn't matter. A soft copper wire can cut through hardened steel. Complex Geometries: Non Conventional Machining Process Ppt
