Stretch Time: Take a Flat Layout A flat layout is the prediction of what the finished part, shown in Figure 1b, shown in Figure 1a looks like before it is bent. Bend Radius - As a rule, inside corner bend radius should be equal to material thickness. Bend Relief - When a bend is made close to an corner edge the material corner may tear unless bend relief is given. It is quite common to find a gusset of sorts in the corner( bend region) of sheet metal parts to stiffen the part.
Sheet metal has memory and must be over- bent to achieve the desired— unrestrained— bend angle. When two edge flanges intersect, a corner is formed.

There are a two major factors that affect how tight you can make the internal radius of a bend in a piece of sheet metal: The hardness of the metal. Nov 18, · Watch Solidworks Corner Relief. During bending, the sheet metal must bridge fully across the V die ( see Figure 2). Because the " sheared" portion of a cut sheet metal part has a high burnish, cracks are less likely to form on the outside of a bend ( not to be confused with orange peeling).
