Abstract: A system and method for accomplishing combined electro-erosion and mechanical cutting of a workpiece which includes an outer metallic jacket and a non-metallic inner core. An elongated wire electrode is provided and is unwound from a supply spool through a pair of forming rollers, during which a specified polygonal and cross sectional shape with a textured outer surface is imparted upon the electrode. Pairs of feed rollers are located to each of supply and take-up sides relative the workpiece, and with the electrode being guidably extended between each of the pairs of rollers. Tensioning rollers are also located on each of the feed and take-up sides of the electrode. An electrical current generating and delivery component is provided in communication with the electrode which electro-erodes the outer metallic jacket of the workpiece.
