In metal fabrication, metal folding; the transformation of flat material sheets into 3D structures has gained a lot of popularity in recent years. Sheet Metal Bending and metal folding have emerged as essential manufacturing techniques based on a broad range of materials and thicknesses. Bending and folding techniques accomplish material shape transformation by inducing changes in the required combination of surface topology and geometrical aspects of the material. However, these techniques are often limited by: inherent processing constraints, the type of material, the material thickness as well as the rational design or pattern of the product to be manufactured. The main purpose of this article is to compare the difference between metal folding and bending techniques based on the material type and the material thickness.
