Abstract

The geometrical accuracy and the surface quality of sheet metal parts as well as the tool wear are influenced by process parameters and by static and dynamic interactions between the press and the tool. Therefore the qualitative characterization of the machine behavior is of high importance for both press manufacturers and press operators. Within research project (Behrens et al. in Entwicklung und Erweiterung standardisierter Messverfahren zur statischen und dynamischen Pressenvermessung. Final Report of the AiF Research Project 13742 N, 2005), a procedure for the measurement of the static machine behavior has been developed, which for the first time allows the standardized measurement of the ram deflection and the bolster plate deflection along with previously standardized characteristic values. The determination of the procedure as measurement directions and the automated evaluation of the measurements ensure not only reproducible results but also easy comparison of two machines. Additionally a new procedure for the measurement of the dynamic press behavior has been standardized which allows the comparison of the static and the dynamic characteristic values.
