Abstract：

The single-pass incremental forming of hole-flanging for 1060 aluminum plate with a certain thickness was studied by software DYNAFORM, and the influences of prefabricated hole diameter d0 on the distribution rules of flanging height and wall thickness with different flanged hole diameters dm were investigated. The results show that when the flanged hole diameter dm is constant, the wall thickness distribution of flanged part exhibits a certain deformation characteristics while changing the prefabricated hole diameter d0. The typical forming characteristics include linear thinning, uniform distribution and central thinning, and the calculation formula of the critical prefabricated hole diameter d0临界 and the flanging height of single-pass incremental forming of hole flanging under different flanged hole diameters dm were obtained. The results find that when the plate is not thinned in the middle, the flanging height is in good agreement with the theoretical calculation formula, and when the plate is thinned in the middle, the flanging height is greatly different from the theoretical calculation formula and needs to be corrected. Furthermore, the physical experiments were conducted by a incremental forming CNC machine tool, and the experimental results verify the credibility of the simulation results.
