Abstract
A method of forming an eroded pattern on a metal part using Electrical Discharge Machining (EDM) comprising: forming a pattern of electrodes on the end of a piece of electrode material by using wire EDM, the pattern of electrodes being the pattern to be eroded on the metal part or being a portion of the pattern; and mounting the metal part for EDM with the pattern of electrodes being mounted for use as electrodes and the erosion of the pattern or portion of the pattern provided by the pattern of electrodes by EDM in the metal part.
