ABSTRACT:
In a wire cut electric discharge machining method, feeding units having wire electrode feeding mechanisms are provided for wire electrodes different in diameter, respectively. The feeding units are moved, one at a time, to a wire electrode feeding path by cylinders coupled detachably to thereto, respectively, whereby the wire electrodes different in diameter are automatically replaced with each other, and machining conditions are automatically selected according to the diameter of a wire electrode and a machining process which are to be used. Therefore, the workpiece can be machined with the wire electrode most suitable for the given machining configuration. Thus, the method is high in machining accuracy and in machining efficiency.
