The safety zone for sheet metal bending refers to the range of deformation and the operational parameters that the material can withstand to ensure that no fracture or other form of damage occurs during the bending process. Properly understanding and adhering to this safety zone is crucial to maintaining the integrity and functionality of the sheet metal.

If there is a need to design holes on the sheet metal, it is essential to consider the potential deformation that can occur during the bending process. To prevent deformation of the holes when bending, it is necessary to reserve an area at the edge of the bend that is at least twice the thickness of the steel plate. This reserved area acts as a buffer zone, absorbing the stresses and strains induced by the bending operation and thereby protecting the holes from distortion. Ensuring this safety margin not only maintains the precision of the hole placement but also contributes to the overall structural integrity of the bent sheet metal part.
