Electrochemical machining is the reverse of electroplating. An electrolyte works as a current carrier, and the high rate of electrolyte flow in the tool-workpiece gap washes metal ions from the workpiece (anode) before they have a chance to plate onto the tool (cathode). Modification of this process are used for turning, facing, slotting ...
