With these visualization methods, the process is usually designed to reach wide process window. Due to changing friction through rising temperatures in the tools, tool wear or batch to batch variations in the material, the process window is reduced again. Therefore new methods are needed to keep the process inside the process window. The paper deals with a possible approach of keeping the process inside these windows. The proposed approach tries to unite the measurement of possible influence factors like the batch to batch variation of material properties with a feedback control to eliminate the non-measurable influences. The measurement of the material properties is done by a measurement system based on eddy-currents, while the needed measurement for a feedback control is done with an optical system. Finally the paper will show the experiences with the proposed system, as well as it will show the prerequisites for such a system. 17th International Conference on Metal Forming, Metal Forming 2018 in Toyohashi, Japan (September 16-19, 2018) Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International http://creativecommons.org/licenses/by-nc-nd/4.0 ethresearch Deep drawing ethresearch Control ethresearch Material properties ethresearch Fischer Pascal joint author Heingärtner Jörg joint author Renkci Yasar joint author Hora Pavel joint author Procedia Manufacturing, 15 Amsterdam : Elsevier pp. 949-954 2351-9789 http://hdl.handle.net/20.500.11850/286728 text/html WWW-Backlink auf das Repository (Open access) 1 Conference Paper ethresearch ETHRESEARCH 856 40 http://hdl.handle.net/20.500.11850/286728 text/html WWW-Backlink auf das Repository (Open access) ETHRESEARCH 700 1- Fischer Pascal joint author ETHRESEARCH 700 1- Heingärtner Jörg joint author ETHRESEARCH 700 1- Renkci Yasar joint author ETHRESEARCH 700 1- Hora Pavel joint author ETHRESEARCH 773 0- Procedia Manufacturing, 15 Amsterdam : Elsevier pp. 949-954 2351-9789 BK010053 XK010053 XK010000 ETHRESEARCH ETHRESEARCH ETHRESEARCH Conference Paper Open access
