The rim zone damage of cemented carbide is decreased by changing pulse mode in wire EDM. Thereby the current raise velocity is significantly increased while the discharge duration is shortening. The decrease of surface roughness leads to more efficient processing. 2. High performance milling of cemented carbide with diamond tools leads to more efficient production in the mold and die production. The process stability is high and the quality requirements are fully met. Optimal process control is necessary.deHartmetallWerkzeug- und FormenbauVerschleißschutzFunkenerosionDrahterosionSenkerosionRandzonenschädigungVierpunkt-BiegebruchversuchFräsenHSC-Fräsencemented carbidemold and die productionwear protectionelectrical discharge machiningwire electro discharge machiningdie sinking electro discharge machiningrim zone damagefour point bending testmillinghigh performance milling620670conference paper
