Flexible flanging is a novel forming process by local continuous loading, but its process law and planning method are not perfect. Based on the characteristics of aviation sheet metal parts, the feature flanging parts were designed. Simulation of flexible flanging was conducted on the Abaqus platform, and the influence of key process parameters such as rolling pass numbers, the angle distribution of each pass, roller diameter, and rolling speed on forming quality were obtained. Considering the forming efficiency, the process parameters were optimized and verified by experiments. The results show that the forming quality of flexible flanging can be significantly improved with low cost by optimizing key process parameters, and the forming efficiency can be improved to a certain extent.

Key words: flexible flanging, sheet metal part, process parameter, forming quality, forming efficiency
