Sheet metal bending bending of sheet metal is a common and vital process in manufacturing industry. Similar to other metal forming processes bending changes the shape of the work piece while the volume of material will remain the. This is done through the application of force on a workpiece.

The force must exceed the material s yield strength to achieve a plastic deformation. Bends specified as angles may be tolerance at plus or minus one half degree at a location adjacent to the bends. There are multiple manufacturing processes that sheet metal can be formed by bending curling incremental sheet forming laser cutting perforating press brake forming punching roll forming rolling spinning stamping water jet cutting.
