Abstract:
A method for electric discharge machining (EDM) with a ductile carbonaceous electrode, to automate roughing, finishing, polishing and texturing operations on a electrically conductive material. The EDM method comprises using a ductile electrically conductive electrode made of carbon-polymer composite material. Prior to electric discharge machining, the electrode is made by heating uniformly a prescribed volume of said ductile electrode material, at a temperature close to the melting point temperature of the polymer matrix. The composite material is then molded into the desired electrode shape by pressing the soft material against a template, a mold model, a replicate of the workpiece or part of the workpiece. The formed electrode is then used to machine the desired shape and surface finish on the said workpiece using proper electric discharge machining techniques. When the dimensions and surface of the electrode are altered by wear, the same electrode can be rectified quickly and repetitively, by following the initial procedure of softening and pressing until the workpiece is complete.

Abstract:
An electrode for discharge surface treating (10) is formed by mixing cBN powder (11), which is an electrically insulating hard substance, with Co alloy powder (12), which is a conductive substance, for charging into a press die, and by compression-molding the mixture; a hard coating (20), consisting of cBN and Co alloy, both high in hardness even under a high-temperature environment, is formed on a material to be treated (16) by generating discharge between the electrode (10) and the material (16) by using a discharge surface treating power supply (17).
