Abstract: Through simulation experiments on hemming qualities for curved surface hemming and curved edge hemming under different flanging sheet sizes, limit values of flanging sheet size are decided for different curvature radius. The values of corresponding flanging length and hemming width are given then. A hemming feature panel is designed based on the standards. The experiment results demonstrate that, the values of designed parameters are reasonable and the feature panel obtains favourable hemming effect.

Key words: aluminum alloys, hemming, flanging, process dimension, design standard
