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.
Claims7
In a method of electrochemical machining in which a work blank member and a cathode member are disposed opposite each other in an electrolyte, a pulsed electric current having a pulse width of 0.01 to 10 ms and a duty factor of not more than 0.5 is passed between said members while one of said members is moved relative to the other member, the cathode member being a thin wire having two end portions mounted on a support and a central portion intermediate said end portions, the improvement which comprises said central portion being laterally offset from a straight line connecting said end portions.
