Abstract：

The trimming line unfolding and flanging forming simulation application (TUA) based on Pro/ENGINEER platform was developed using secondary development tool kit named Pro/TOOLKIT. It achieved the seamless integration between TUA and Pro/ENGINEER, avoided the data loss of files converted between different systems. Based on the Pro/ENGINEER environment, the key technologies, such as dynamic material library, multi-regional unfolding, constraint definition and data management were studied. The process parameters were considered by the adopted finite element inverse approach solver which could be applied to predict three-dimensional trimming line and flanging formability. Finally, it was proved that TUA could mostly meet the requirement of sheet metal production process for the simulation result is consistent with practical production in the experiment.
