Abstract：

The numerical control incremental sheet forming technology of asymmetry square component was studied based on finite element method and experiments, which included the difference of forming limit diagrams and the change of wall thickness between single-stage and double-stage forming, and the influence on forming quality by different forming paths in double-stage forming. It was found that the formability of components can be improved by double-stage forming, but the influence of forming angle of components wall on formability should be considered to avoid excessive thinning in the wall and sinkage in the bottom of components due to wide variance in the radial direction.
