The forming characteristic in the single-point incremental forming of a complex shape

Incremental sheet forming is popularly applied because of its reduced cost, flexibility, and applicability for small batch production. To reduce the manufacturing cost and time consumption, the incremental forming of a complex shape is implemented by combining two forming methods into one process: positive and negative incremental forming. The experiments were done to confirm the applicable ability of the method with the material aluminium Al3004-P. The finite element simulation was done with the ABAQUS explicit finite element code, and its results were compared with the experimental results.
