ABSTRACT:
A novel electroerosion machining method and apparatus makes use of an elongate, open-ended tubular casing of a heat-resistant material retaining therein discrete metallic bodies (e.g. granular particles, flakes, fine powdery particles or broken wires) in a packed state. The casing is axially juxtaposed with a workpiece to define a machining site in the region of the latter proximate to the open-end portion of the casing and traversed by a machining liquid. A conventional electroerosion power supply furnishes a machining current between the workpiece and the discrete metallic bodies in the casing successively fed into the machining site to electroerosively remove material from the region of the workpiece against the discrete metallic bodies functioning as continuously consumed eletroerosion electrodes in the machining liquid medium. The casing and the workpiece are relatively displaced three-dimensionally to cause the open-end portion of the casing to sweep over the workpiece to form a desired cavity of desired shape therein.
