"Electrical Discharge Machining (EDM) is a non-contact manufacturing process that uses electrical discharges (sparks) to erode material from a conductive workpiece. It typically involves a tool electrode and a workpiece submerged in a dielectric fluid, with high-frequency electrical pulses passing between them. When these pulses are applied, the intense heat created by the electric sparks vaporizes or melts tiny bits of the workpiece material, precisely shaping it."
