ABSTRACT:
In a method for electrochemical machining effected by disposing a work blank and a cathode opposite each other across a gap in an electrolyte and causing a flow of electric current to pass between said work blank and cathode, an improvement is disclosed which consists in using, as the cathode, a thin wire having a non-linear shape and, as the electric current, a pulsed electric current and thereby machining the work blank to a desired shape.
