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. The textured surface of the electrode preferably exhibits teeth which mechanically abrade, when advanced longitudinally in relation to the workpiece, its inner core and in order to cut through and section the inner core.
