introduction to electric-discharge machining(EDM)
Electric-discharge machining is a reproducing forming process, which uses the material removing effect of short, successive electric discharges in a dielectric fluid. […]
What is EDM ?
The EDM is derived from Electrical Discharge Machining. The EDM process as we know it today started in 1770 with the observations of Joseph Preistly. He noticed that electrical discharges had removed material from electrodes used in his experiments. This is also known as electro-discharge erosion. Later on in the 1940's Soviet researchers developed a [...]
