Wire electrical discharge machining (EDM) is used widely to create punches, mould components, special tooling, extrusion dies, airfoils, medical instruments, gear, tool holders, carbide cutters and thousands of workpieces too numerous to list. Wire EDM Tooling can be used to cut electrically conductive materials to make parts that require a high level of accuracy, intricacy and fine surface finish that is not achievable with traditional machining methods. Wire EDM unit can be programmed to cut complex shapes while there is no cutting force on the workpiece and no residual stress. There is little to no change in mechanical properties of the material. Wire EDM technology virtually leaves no thermal effects on the surface. Wire EDM is best to cut extremely hard materials and rarely calls for expensive work holding fixtures. The Working of Wire EDM Wire EDM is an electrothermal production process where a thin single strand metal wire along with deionized water allows the wire ...
