High Precision Process Chains for the Mass Production of Functional Structured Surfaces

The Leibniz-Institut für Werkstofforientierte Technologien -- IWT (engl. Leibniz Institute for Materials Engineering) emerged from the former Institute of Hardening Technology in Bremen and is an institution with a rich research tradition of more than 50 years. The overall objective of the IWT is to carry out multidisciplinary basic and applied research in metalworking. The IWT is the only research centre in Germany that has united the three disciplines materials science, process engineering and manufacturing technologies as equal-ranking divisions working together under one roof. Thanks to this structure, the IWT is able to solve technological problems for metalworking companies on the interdisciplinary level without the usual time-consuming process of “coordinate and consent”. Established at the campus of the University of Bremen, the IWT’s know-how is supplemented through close networking with other research institutions and fields of the faculty Production Engineering of the University of Bremen.

In 2018, the LFM was incorporated into the IWT during their admission to the Leibniz Association. LFM is directed by Prof. B. Karpuschewski (Professor at UBRE and Director of IWT), head of department is Dr. Oltmann Riemer; LFM employs about 23 people staff. R&D activities at LFM include diamond turning and milling of metal substrates, plastics and IR materials, precision grinding of glasses and ceramics, polishing of glass lenses and moulds, micro machining by micro milling and micro grinding, surface metrology (interferometry, scanning force microscopy, profilometry, 3D coordinate measuring techniques), as well as modelling and simulation techniques of machining processes.
