Influence of Tooling Geometry on the Quality of Aluminum Sheet Shearing Surface 970716
The present research is concerned with the quality of the shearing process, which is an integral part of automotive vehicle body stamping. Experiments were done to analyse the influence of the gap between the cutting edges and the geometry of the cutting blades, on the quality of the sheared surface. Experimental results are presented as microstructures of polished samples. To predict the quality of sheared surfaces, a numerical code based on solid mechanics equations, elastoplastic flow theory and cummulative theory of damages was created.
