Relief height is generally kept greater than two times of sheet thickness plus bend radius.
Sheet metal corner relief design.

Understanding corner relief design flexibility 2 the contour flange is created using the auto miter option and the seven edge loop of the polygon is selected.
Relief helps to control sheet metal material behavior and to prevent unwanted deformation during unbend operations.
Bend relief is provided at the end of bending edge in sheet metal design to avoid any crack tearing in the corner.
To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.
A 1 degree tolerance on all bend angles.
Bends in sheet metal are manufactured using sheet metal brakes.
When designing parts for laser cutting one should not make holes smaller than the thickness of the material.
When sheet metal makes a transition from a bend to a flat surface or to another bend it tends to rip and tear.
In general a minimum bend relief is equal to the material thickness plus the inside bend radius.
Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured.
