Abstract：

The large plate requires to be formed by large size forming equipment, and the multipoint forming has the characteristics of both accumulated forming effect from the single point incremental forming and free reconstruction of multipoint forming die. Then, the forming effects were simulated numerically by four different forming technologies, and the experimental researches were carried out. Furthermore, the experimental results were scanned by a 3D laser scanner and compared with simulated results. The results indicate that the forming method by moving both side pins together is better than that by first adjusting one side pin position and then moving it for a doublecurvature plate. The influence of the forming path on the forming effect is unobvious, but the gradual changes of forming force are greatly affected by the driving model of pins.
