ABSTRACT:
An electrical discharge machining system is improved by incorporation of an apparatus which permits a machining core to be subdivided into a plurality of sub-cores for separate removal. The invention permits automatic core removal in cases where cores were manually removed in the past, such as where the cores were too large, heavy or irregularly shaped to be handled by the known automatic core disposal apparatus.
