Abstract
A core removing device for a wirecut electrical discharge machine having top and bottom universal movement tables that control the orientation of respective top and bottom guides, each guide being located generally within a nozzle which is surrounded by permanent magnet or an electromagnet. The guides and nozzles are disposed on opposite sides of a workpiece and guide a wire electrode that is used to perform an EDM operation as it travels along a cross section of the workpiece during machining. The relative orientation of the top and bottom guides will determine the angle at which the workpiece is cut and the shape of the remaining core. Upon completion of the machining operation, the core may be removed from the top surface or bottom surface of the workpiece by proper positioning of the guide nozzle and the controlled energization of the respective magnet, in the case of electromagnets, to attract and hold the core.
