Wire EDM has revolutionized machining. Things that were once impossible to machine are now being done with wire EDM. With wire EDM we can cut any conceivable shape up to 45 degrees taper with accuracies of +/-.0001". Any electrically conductive material can be machined with EDM, even tungsten carbide. An added benefit of wire EDM is that exotic alloys can be machined just as easily as mild steel. Since the wire electrode never comes into contact with the metal, wire EDM is a stress-free machining process. Sommer, president of the largest EDM job shop in North America, has co-authored with his son Steve, a mechanical engineer, Complete EDM Handbook. The handbook is free at their website.
