Electrical measurements in µ-EDM - IOPscience

04/07/2008  Electrical discharge machining (EDM) is the process of removing material from two electrodes, the workpiece and the tool. When these electrodes are submerged in a liquid dielectric bath, the pulses of voltage that are applied to them cause a sequence of breakdowns and recoveries of the in-between dielectric. A pulsed flow of current therefore takes place between the electrodes. Each of
