Zerspanung von Hochleistungswerkstoffen mit ultrasonisch modulierter Schnittgeschwindigkeit

Ultrasonically-assisted-milling and grinding of high-strength metallic and brittle-hard ceramic materials results in a significant reduction of cutting forces and an improvement of the surface roughness compared to conventional cutting. The use of a torsional actuator showed additional improvements in milling. Further investigations will be carried out to extend this to the grinding process. The ultimate goal is the model-based determination of the influence of a vibration superimposition of the tool on the resulting cutting force during milling and grinding.
