The CRC 136 "Process Signatures" presented its research at the OPEN CAMPUS of the University of Bremen on Saturday, June 15, 2019, in a way that is appropriate for laypeople, interactive and in a popular mood. The aim was to exchange information with women and men from Bremen on the research of the CRC, to interest them in the exciting field of research and to promote acceptance for research and research funds. Many interested visitors informed themselves about residual stresses and tried out the Kohlrabi hobbing machine and produced gears from Kohlrabi.
