Numerical Analysis of The Effect of Pin Diameter on Stress Distribution in Active Punch-Type Multi-Point Forming

Abstract: One of the flexible sheet metal forming methods is multi-point forming (MPF). MPF is mostly utilized in automotive and aerospace prototypes to cut down on time and costs. To comprehend the impacts of forming orientation on multi-point formation, two alternative forming orientations have been explored in this work. Deform 3D, a finite element program, was used to model and analyse multi-point forming (MPF) orientations. The V-type shape was created using 0.5 mm thick sheet metal made of aluminium 1100. According to the necessary load of sheet metal in simulations, three different diameters, 10 mm, 12 mm, and 14 mm, were examined. The findings indicate that, in comparison conventional forming10 mm pin forming was a more suitable forming type for this shape.
