Abstract
A method for electroerosion machining includes providing an electrode assembly comprising an electrode body having a tube-shaped body that defines a hollow interior and one or more inserts affixed to the electrode body to form a cutting surface on the electrode assembly, positioning the electrode assembly adjacent a workpiece to be machined, and providing power to the electrode assembly so as to energize the electrode assembly, with the electrode assembly and the workpiece being at opposite electrical polarities. The method also includes advancing the electrode assembly through the workpiece, with a working gap being maintained between the inserts and the workpiece across which a pulse electric current is passed to remove material from the workpiece, wherein, upon advancing the electrode assembly through the workpiece, a core is formed that is completely separated from a remainder of the workpiece and is contained within the hollow interior of the electrode body.
