EDM (Electro-discharge machining)  

Definition

  • 1. Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges (sparks). (WIkipedia). 2. Electrical Discharge Machining (EDM) is a nonconventional machining process used primarily for tasks that would be unachievable with conventional methods. It uses electricity to erode the surface of conductive materials. Since no tool physically contacts the workpiece, EDM can maintain fine surface finishes even on intricate and delicate parts. (https://www.xometry.com/resources/machining/electrical-discharge-machining/). 3. Electrical Discharge Machining (EDM) is a manufacturing process utilized to eliminate material from a workpiece by employing a succession of rapid electrical discharges between electrodes within a dielectric fluid. This method is particularly effective for producing parts that are challenging or impractical to machine with conventional techniques, as it depends on electrical forces instead of mechanical ones. (https://www.iqsdirectory.com/articles/edm/edm-machining.html). 4. Electrical discharge machining (EDM) is a non-traditional machining process based on removing material from a part by means of a series of repeated electrical discharges between tools, called electrodes, and the part being machined in the presence of a dielectric fluid.
