Electrical Discharge Machining DVD

Electrical discharge machining (EDM) shapes metal by creating sparks that melt tiny portions of the workpiece, and is an exceptionally diverse process that generates no cutting forces. EDM is especially useful in the production of fragile parts that cannot take the stress of conventional machining. This program examines the EDM process and the two primary forms of electrical discharge machining — ram EDM and wire EDM.

Thermal and Abrasive Waterjet Cutting DVD

Thermal cutting processes use heat for cutting. The abrasive waterjet process uses no heat, but cuts by abrasive erosion. All these processes provide precision non-contact cuts in a wide variety of materials, and cut in single pass, rather than multiple passes. To better understand the various cutting processes, this program examines, explains, and compares oxy-fuel cutting, plasma cutting, laser cutting applications, and abrasive waterjet cutting.
