英文摘要
Die zentrale Zielsetzung des vorliegenden Projekts ist die Erweiterung der Formgebungsgrenzen beim Drückumformen durch Laserstrahlunterstützung. Zu diesem Zweck sollen ein Hochleistungsdiodenlaser in eine konventionelle Drückmaschine integriert und Prozeßuntersuchungen durchgeführt werden. Durch die gezielte, lokal begrenzte Einbringung von Wärmeenergie mittels Laserstrahlung in die Umformzone können erheblich höhere Umformgrade erzielt werden, ohne daß ein Werkstoffversagen in Form eines duktilen Bruchs auftritt. Im Rahmen von Simulationen und Experimenten sollen die Temperatur in der Umformzone und die tribologischen Bedingungen als zentrale Einflußgrößen auf das Umformergebnis untersucht werden. Einen zweiten Projektschwerpunkt stellt die Erarbeitung von Konzepten zur direkten Integration von modernen Hochleistungsdiodenlasern in konventionellen Drückmaschinen dar. Die entwickelten Konzepte werden prototypisch umgesetzt und somit verifiziert.
