Abstract
In order to increase the productivity of the production process of steel wires, the process chain of notch rolling and cyclic bending is fundamentally analyzed. During notch rolling, notches are formed on both sides of a sheet metal strip, in whose areas the material fatigues and forms cracks during the subsequent fulling process. The numerical and experimental implementation of both process steps enables the identification of relevant influencing parameters and their interactions. Parameters taken into account are, among others, the notch radius, notch angle and web thickness in notch rolling, and the bending angle and number of cycles to breakage or to the desired residual web thickness in cyclic bending. Numerical and experimental studies of ductile damage are required to evaluate material separation.
