19th International Conference on Sheet Metal 
The 19th International Conference on Sheet Metal was hosted by the Institute of Manufacturing Technology at the Friedrich-Alexander-Universität Erlangen-Nürnberg March 29th – 31st 2021. Due to the Covid-19 pandemic it was a virtual conference. Nevertheless there were reals sessions with with life presentations enabling discussions and seeing people again. Further information regarding the conference can be found here.
The proceedings have been published by TTP. The volume of KEM can be found here. A limited number of prints may be purchased at 80,00 € plus shipping and handling. Your contact in case of interest is Prof. Dr.-Ing. habil. Dipl.-Inf. Hinnerk Hagenah.
