To meet the modern demands for lightweight construction and energy efficiency, hard-to-machine materials such as ceramics, superalloys, and fiber-reinforced plastics are being used progressively. These materials can only be machined with great effort using conventional machining processes due to the high cutting forces, poor surface qualities, and...
To meet the modern demands for lightweight construction and energy efficiency, hard-to-machine materials such as ceramics, superalloys and fiber-reinforced plastics are being used progressively.

In vibration-assisted milling (VAM), an additional high-frequency oscillation is superimposed on the kinematics of a conventional machining process. This generates oscillations of the cutting edge in the range of a few micrometers, thereby causing a high-frequency change in the cutting speed and/or the feed. Consequently, a reduction of cutting for...
Kurzfassung
Die steigenden Anforderungen an die Festigkeit und die Qualität von Bauteilen und die damit verbundene Verwendung hochfester Materialien erfordert die Weiterentwicklung neuer wirtschaftlicher Zerspanungstechniken. Durch eine werkzeugseitige Schwingungsüberlagerung können bei der Bearbeitung von schwer zerspanbaren Werkstoffen die Zerspa...
Megatrends wie die Kundenindividualisierung erfordern eine gesteigerte Wandlungsfähigkeit in der Produktion. Mobile Roboter zeigen hier großes Potenzial durch ihre Ortsungebundenheit, Skalierbarkeit und Konfigurationsfähigkeit. Vorgestellt wird ein Ansatz zur dynamischen Adaption durch modulare Softwarebausteine (Apps). Auf dieser Basis wird die In...
One of the main goals of the collaborative research project FORobotics is to gain new insights into human-related aspects and pro-cesses that might be essential to the development and effective implementation of cooperative mobile robots. In order to achieve this goal, a qualitative, task-related work system analysis was conducted as a first step....
Structural lightweight construction is increasingly utilized in the aerospace and automotive industry. Hybrid structures have great potential, especially with regard to load-specific component layouts. Usually, a surface pre-treatment is applied prior to joining dissimilar materials to improve bonding mechanisms such as form closure. In previous st...
Kurzfassung
Durch die Miniaturisierung von Elektronik besteht die Möglichkeit, diese flexibel in Werkzeugen und Spannmitteln zu integrieren. In diesem Beitrag werden verschiedene Ansätze wie sensorische und aktorische Werkzeuge oder intelligente Spannmittel, mit denen die Flexibilität und Produktivität gesteigert werden können, exemplarisch vorgest...
Friction Press Joining (FPJ) is a suitable method for producing composites of aluminum and thermoplastics in lap joint configuration, which is based on modified Friction Stir Welding (FSW). During the joining process, a rotating cylindrical tool is pressed onto an aluminum surface. The resulting friction generates heat that is conducted to the bond...
