ABSTRACT:
A rapid method for fabricating a precision electrical discharge machining (EDM) electrode (71). A set of master parts (31, 32) in the shape of the EDM electrode is formed using stereolithography or other rapid prototyping techniques (106). The master parts are assembled and a flexible material is molded (109, 56, 57) in them to form a flexible mold (111, 61). The flexible mold is then filled (115) with electrically conductive powder and the powder is cold isostatically pressed (117) to solidify it and form the EDM electrode.
