ABSTRACT:
An EDM method and apparatus wherein a localized magnetic field is produced so as to be concentrated at least predominantly on a region of the EDM gap which constitutes only a limited portion of a preselected entire area of juxtaposition between the tool and workpiece electrodes. The region of concentration of the localized magnetic field is successively shifted to sweep it over the entire area of juxtaposition between the electrodes. A control device is provided to control at least one parameter of production and sweeping of the localized magnetic field in response to at least one process parameter of the EDM process.
