Bending, flanging, and hemming of aluminum sheet—an experimental study

Hemming is often used as the last stage of stamping operations. It is used either to improve appearance (to create a smooth edge rather than a razor edge with burrs) or to attach one sheet metal part to another. Hemming is defined as folding of bent or flanged sheet 180° or more. However, the deform...

Description
Summary:Hemming is often used as the last stage of stamping operations. It is used either to improve appearance (to create a smooth edge rather than a razor edge with burrs) or to attach one sheet metal part to another. Hemming is defined as folding of bent or flanged sheet 180° or more. However, the deformation mechanism, and hence the process, is different and more complex than simple bending and flanging process. Therefore, very little information is available in research literature, and most of the hemming dies are designed based on trial and error. This paper gives the results obtained from the hemming experiments that were conducted at the Engineering Research Center for Net Shape Manufacturing (ERC/NSM) by using Aluminum Alloy 1050.
