Innovative Prozesse zur wirtschaftlichen und schädigungsarmen Bearbeitung von Hartmetall

In the presentation, the results of two research projects are presented: 1. 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.
