Abstract:
A system for accomplishing combined electro-erosion and mechanical cutting of a workpiece having an outer metallic jacket and a non-metallic inner core, said system comprising:an elongated wire electrode having a specified polygonal and cross sectional shape with a textured outer surface; at least a first pair of feed rollers located to one side of the workpiece and a second pair rollers located to the other side, said electrode being guidably extended between each of said pairs of rollers; an electrical current generating and delivery component in communication with said wire electrode, through at least one of said rollers, and such that said electrode exhibits current carrying and electro-erosive capability when arranged in proximity to the outer metallic jacket of the workpiece; and said textured surface of said electrode further exhibiting mechanically abrasive properties when advanced longitudinally in relation to the inner core of the workpiece and in order to cut through and section the inner core.
