  • Patent number: 4762974
    Abstract: An electroerosion discharge machine with multiple lead power supply is provided, which has a multiple wire electrode feed in which all of the wire electrodes are electrically insulated from one another. By insulating the wire electrodes from each other throughout the device, differing currents and other differing parameters such as tension can be applied to each wire so that the most appropriate condition may be used to erode a given workpiece made out of a particular material. The present invention also permits workpieces of varying heights to be simultaneously cut as well as allowing the various sized wire electrodes to erode the workpiece at a wire speed that is most appropriate for the given task at hand, as well as other important parameters which can be selected independently for each wire.
