Features 01
Expected Problems
Aren't you having these kinds of problems in press forming?
? Product quality is unstable due to frequent occurrence of dimensional deviations caused by springback.
? Die shape tuning is extremely time-consuming and expensive, and reduces production efficiency.
? Have not established effective countermeasures because it isn't possible to identify the areas that cause springback.
Features 02
Technology highlight
? High-accuracy back-calculation of the bottom dead center (BDC) stress distribution using 3D shape measurement data after springback of formed parts (Fig. 1).
? Calculates the difference between the BDC stress distribution by elasto-plastic FEM analysis and the measurement-based stress distribution (Fig. 2).
? Identifies the areas of stress that cause springback by analyzing the differential stress distribution (Fig. 2).
? Stress can be effectively controlled by changing the part and die geometry at the specified areas.
