Method and device for controlling an electro-discharge machining process

摘要

The invention relates to a method and a device for controlling an electro-discharge machining process, in the case of which a workpiece electrode (2) forms a machining gap (G) with a tool electrode (1). The tool electrode (1) and the workpiece electrode (2) are displaced relative to one another so that a recess is formed in the workpiece electrode (2) as a result of electrical discharges across the machining gap (G). A localised magnetic field acts in a localised region on the machining gap (G) and is successively displaced so that the entire gap region is covered. At least one parameter for the action and displacement of the magnetic field is controlled as a function of a process parameter. <IMAGE>
