General term for the removal of material from a workpiece by the action of an electrical power source and ion transfer inside an electrolytic fluid; it is essentially the opposite of electroplating; metal ions are washed away from the surface of a workpiece (the anode) via a pump that circulates electrolyte fluid fast enough so the metal ions do not have the chance to plate themselves onto the tool (the cathode); the tool is the same shape of the cavity that is produced in the workpiece it is generally used to machine complex cavities and shapes in high-strength materials and does not leave burrs
