, often referred to as spark machining or spark erosion, is a non-traditional manufacturing process that removes material from a workpiece using controlled electrical discharges (sparks). Unlike conventional milling or turning that relies on physical contact and mechanical force, EDM is a thermal erosion process where a series of rapidly recurring current discharges between two electrodes melts and vaporizes microscopic amounts of material. How EDM Works
A power supply creates high-frequency electrical pulses across a tiny gap (0.005 mm to 1 mm) between a tool electrode and the workpiece.
When the voltage reaches a "breakdown" point, the dielectric fluid ionizes, forming a plasma channel. The resulting sparks generate localized temperatures between 8,000°C and 12,000°C , vaporizing the material.
