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

The University of Bremen (UBRE) was founded in 1971. In the course of its relatively short history it has developed into the science center of North West Germany. When it was founded it broke new ground in many ways, earning the label “Bremen Model”. Some of these breakthroughs have now become standard features of modern universities. For instance: interdisciplinarity, research-based learning in projects, and social commitment.

The Laboratory for Precision Machining LFM is a standalone research facility of the University of Bremen and the Leibniz-IWT. LFM is directed by Prof. B. Karpuschewski (Professor at UBRE and Director of IWT), head of department is Dr. Oltmann Riemer. 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.

Basic research at LFM is focusing on diamond machining of complex optical moulds, material removal mechanisms, diamond turning of steel alloys, polishing processes, and machining of micro components. These types of project are being funded by national sponsors like German Research Foundation DFG or the Federal Ministry of Education and Research BMBF as well as the European Commission. Furthermore, there are many industrial R&D projects, e.g. diamond machining of large aspheric and free form mirrors, development of ultraprecision multi-axis milling processes, manufacture of diffractive optical elements or precision grinding of aspheric mirrors and moulds.
