In this paper, the occurrence of recoil and surface warp during the flat surface - straight edge hemming process is investigated. A general - purpose finite element code ABAQUS / Standard is used to simulate the hemming operations. Reverse bending and springback are the fundamental mechanisms that cause surface warp and recoil. Recoil and warp are not independent. One parameter, final equivalent warp, is used to represent both. Pre - hemming target ending position is proposed based on the minimization of the final equivalent warp. The influence of the geometrical and process parameters on recoil and warp are also discussed.
