Abstract
This paper presents experimental results of a novel approach for measuring the forces in forming machines. The basis for this approach is the development and arrangement of a modular measuring system which can be integrated between tool and ram of the forming machine. The modular character of the system allows it to be applied to any tool size and shape. A special focus of the application presented here is the recording of the surface and temporal distribution of the forces and their significance with regard to component quality. In this way, it can be shown how changes in the process affect the distribution of force, for example by deliberately detuning the tool. In addition, statements on time and place can be derived from possible crack formation. In this way, the measuring system can be used for continuous process monitoring.
