The transregional collaborative research centre (Transregio) 73 is a joint research intiative. Each of the involved universities, the Technical University of Dortmund, the Leibniz University of Hannover and the Friedrich-Alexander University of Erlangen-Nuremberg which is also providing the speaker of the initative has 4 research institutes or chairs in the centre.
Vision
The vision of the Transregio 73 is the development of a new manufacturing technology, sheet-bulk metal forming (SBMF), that will unite the advantages of sheet and bulk metal forming processes in term of flexibility and possibilities. The new technology will therefore be a great progress beyond the limitations each of these two groups of forming processes has at the moment. SBMF is the plastic changing of the shape of a plain semi-finished product not changing the specimens integrity. During the forming process both two- and three-axial strain- and stress conditions as well as changes in shape occur simultaneously or shortly after each other.
The research work is targeted at the manufacture of geometrically complex parts with variants and functional elements from thin sheet metal through forming. The intial sheet thickness shall be below 3 mm. With the newly developed technologies the following goals, that represent focii of todays technological development, shall be reachable:
- Functional integration and extension of sheet metal parts, increase in workpiece complexity
- Shortening of process chains and increas of robustness and reliability
- Improvement of economic efficiency
- Productdevelopment / lot size and production's ability to adapt to variations
