Die Implementierung von Lösungen der datengetriebenen Produktion in KMU stellt oftmals eine große Hürde dar, da häufig das notwendige Know-how nicht vorhanden ist. Mit dem Projekt „Plattform dataPro“ werden eine Transferumgebung zum Domänenwissen und Implementierungsansätze im Bereich der datengetriebenen Produktion geschaffen. Die Grundlage bilden Demonstratoren. Am PTW der TU Darmstadt wurde ein solcher Demonstrator zur KI-basierten Echtzeitüberwachung einer Motorspindel entwickelt, der Domänenwissen in einem anschaulichen Anwendungsfall darstellt.
An increased demand for sustainable materials has led to intensive research in the field of three-dimensional paperboard forming. To date, this work has focused on forming processes with shape-giving tools. However, individual shapes are often required, especially for large-format products. Incremental forming can be used in metal processing for small batches. In this article, the technology of incremental forming is transferred to paperboard. The results showed that elevated moisture content and a superimposed counter pressure significantly increased the forming limits. In addition, the use of polymer layers increased the shape accuracy. An extended understanding of the underlying mechanisms was achieved by analyzing the forming behavior. In uniaxial and biaxial characterization tests the influence of the moisture content on the forming behavior was investigated with conditions relevant for incremental forming. It was found that the bulge test is suitable to determine the most suitable moisture content regarding the forming limits and the spring back behavior in incremental forming. In addition, it was observed that the bearable elongations during the incremental forming of paperboard are significantly higher than in the established characterization tests. The reason for this is a compression of the fiber network during forming.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
