Parameter based process optimisation of bending and blanking operations



Project Status: Active

Members


The production of safety-related components with a complex geometry by blanking and bending is a challenge regarding the material as well as the process. This project aims at the development and qualification of a methodology for practically oriented feasibility assessment and computer aided process design of bending and blanking operations on high strength steels. In the second project phase FE models with integrated damage models for the already developed experiments were created. Based on this variant calculations have been performed and the results were used for the development of a programm for process prediction. This programm supplies a forecast about the expected damage based on mathematical approximations. This information can be used in industrial environment to predict the damage behaviour before the start of series production and thus serve for a specific and fast process development.
