Bending

Bending is a common technique to process sheet metal. It is usually done by hand on a box and pan brake, or industrially on a brake press or machine brake. Typical products that are made like this are boxes such as electrical enclosures, rectangular ductwork, and some firearm parts such as the receiver of the AKM AK-47 variant.

Press Brake
Usually Bending has to overcome both tensile stresses as well as compressive stresses. When Bending is done, the residual stresses make it re bend or spring back to its original position, so we have to overbend the sheet metal keeping in mind the residual stresses.
