Sheet Metal Corner Relief Design

You can define corner relief settings during feature creation or you can predefine them in the relief area of the sheetmetal preferences dialog box or using sheet metal parameters.

Sheet metal corner relief design.

Rip corner relief and conversion creo creoparamet. Bends in sheet metal are manufactured using sheet metal brakes. The resulting model faces are all nicely trimmed and all have appropriate corner relief in the flat pattern. Relief helps to control sheet metal material behavior and to prevent unwanted deformation during unbend operations.

When designing parts for laser cutting one should not make holes smaller than the thickness of the material. To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend. Relief height is generally kept greater than two times of sheet thickness plus bend radius. Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured.
