Reconsidering Copper Electrodes

Although most U.S. moldmakers machine EDM electrodes from graphite, one shop reports that copper creates less of a mess, reduces flaws resulting from DC arcing, and imparts a better surface finish. B A Die Mold first experimented with machining EDM electrodes from copper rather than graphite in the early 2000s, and the company hasn't looked back since.

Graphite vs. Copper Electrode Material for EDM

Depending on the sinker EDM used, the graphite electrodes completed the burns ranging from 28 to 171 percent faster than the copper electrodes. The copper electrodes completed the burn in an average of 4 hours and 29 minutes, whereas the graphite electrode had

Fanuc explains the benefits of Electronic Discharge

With wire EDM, electrodes run through a wire which then form the sparks to cut the material into a desired shape. Over recent years, it has built up a reputation as a precise, efficient and cost-effective machining method and as an alternative to milling, it can cut hard materials to an extremely accurate degree, producing sophisticated parts for a range of industries.

Fabrication of MMC material for EDM electrode

Recently, new approach for fabrication of EDM electrodes using rapid prototyping (RP) technology has been investigated with one main objective which is to reduce production cost, due to RP technology's ability to produce three dimensional objects from its CAD

Setting the Record Straight With Metal Disintegration

Material is removed from the workpiece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric liquid and subject to an electric voltage. One of the electrodes is called the tool-electrode, or simply the "tool" or "electrode," while the other is called the workpiece-electrode, or "workpiece."

EDM 101: Electrical Discharge Machining Basics

Obviously, any workpiece that's going to be machined with EDM has to be electrically conductive, but there's more to the material limitations of electrical discharge machining than that. For one, certain materials, such as high-nickel alloys—like those found in the aerospace industry—and carbide materials can present a greater challenge for EDM compared to standard tool steels.
