Abstract：

Based on software DYNAFORM, the outer edge flanging of 1060 aluminum sheet in a single pass incremental forming was simulated and studied, and for a certain thickness of sheet metal, the influence of different blank diameters D on the forming result was investigated when the outer edge flange diameter was dm in the incremental forming. The results show that for the outer edge flanged parts with a certain flanging diameter dm, with the increasing of the blank diameter D, the distribution state of the wall thickness for part sequentially presents three characteristics such as linear thickening, curve thickening and central thinning. When the wall thickness is reduced in the middle, the forming quality of part is greatly reduced and cannot meet the needs of use. The maximum blank diameter without middle thinning during forming is called the critical flanging diameter dm临界 under this size. At the same time, the research on the outer edge flanging height in the incremental forming shows that the relationship between the flanging height and the blank diameter can be approximated by a quadratic polynomial.
