“…H. Iseki used MS-ISF to get parts with vertical wall, i.e., forming angle is 90° [7]. Duflou et al studied the flow curve in MS-ISF by FEA method, and results show that more material is deformed in MS-ISF compared to single-stage ISF and material in deformation area is not in plane strain state [8].…”

Multi-stage incremental sheet metal forming (MS-ISF) is a good solution to overcome the maximum forming angle of single-stage incremental sheet metal forming. In order to test the formability of MS-ISF, a novel method to get forming limit diagram (FLD) of MS-ISF was proposed based on changing forming strategies. Aluminum alloy AA1060-O sheet was employed to prove the feasibility of the method. Test results show that the method can provide FLD of MS-ISF which is affected by loading path.

“…The conventional forming processes for sheet metal are suitable for producing large quantities of products; nevertheless, large initial investments are economically unsuitable for small-batch products. For this reason, some continuous forming processes have been developed, which could be used to manufacture a number of sheet metal parts with different shapes in condition of low setup cost, such as incremental sheet metal forming process [1][2][3][4] and rolling process [5][6][7][8]. Yoon et al developed the incremental roll forming process composed of two pairs of lower support rolls and one upper center roll to manufacture 3D surface parts [9,10].…”

3D rolling is a novel forming process for manufacturing 3D surface parts by employing a pair of forming rolls as a forming tool. By controlling the nonuniform distribution of roll gap of the forming rolls, residual stress of the sheet metal makes the sheet metal bend in the transverse and longitudinal directions simultaneously. As the roll adjusting radius is much larger than the target transverse curvature radius of the forming surface, the forming roll could rotate around its axis easily, which is suitable for producing 3D surface parts including the wide sheet metal with relatively small transversal curvature radius. In this paper, different roll adjusting radii are investigated for 3D surface parts, and the 3D rolling process has been improved to increase the length of effectively forming region of the forming parts and improve the utilization rate of sheet metal. Finite element analysis models are established; spherical and saddle surfaces are simulated. The corresponding experimental results are obtained. The dimensional accuracy of the forming part is measured, and the differences of the forming processes are analyzed by comparing the simulated results. The comparison and analysis of the forming results show the feasibility of the improved method of 3D rolling process for 3D surface parts.

“…Incremental forming processes based on various forming concepts have been developed through research for diverse industrial applications [1][2][3][4][5]. In addition, an incremental roll forming process based on the principle of bending-dominant deformation that generates minimal thickness strain has been proposed by Yoon and Yang [6].…”
