Bridging the gap between engineering and tryout of sheet metal forming parts by a smart solution

Abstract

When a good simulation solution is found by an engineering department the challenge is to transfer this knowledge properly to the tryout process, because in an ideal process, the tryout would reproduce engineered results in a minimum time. But very often this knowledge transfer exists only of handing over printed simulation reports to the tryout team and then it depends on the interpretation of such a document to reproduce all important information to get similar results in reality. A solution to improve this situation would be to connect engineering and tryout with a smart digital solution, which supports tryout to reproduce the results from simulation fast and easy. The draw-in from simulation solution can be used as target to reproduce the same draw-in at tryout, because if draw-in is matching, then also the material flow is matching and the strain distribution too. To do so a sensitivity analysis based on the found simulation solution should be calculated by variation of the drawbead restraining and binder force and then exported to a smart digital tryout solution. Finally this smart digital tryout solution would provide all required information to tryout that they are able to reproduce the draw-in like engineered as fast as possible to speed up the process by avoiding unnecessary tool modifications. Based on this the gap between engineering and tryout can be bridged in a more efficient way.
