Sheet Metal Corner Relief Design

Bend relief is provided at the end of bending edge in sheet metal design to avoid any crack tearing in the corner.

Sheet metal corner relief design.

A 1 degree tolerance on all bend angles. When designing parts for laser cutting one should not make holes smaller than the thickness of the material. The resulting model faces are all nicely trimmed and all have appropriate corner relief in the flat pattern. Figure 3 figure 4 figure 5 figure 6.

Relief helps to control sheet metal material behavior and to prevent unwanted deformation during unbend operations. Rip corner relief and conversion creo creoparamet. 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. Relief height is generally kept greater than two times of sheet thickness plus bend radius.

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. Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured. To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend. In general a minimum bend relief is equal to the material thickness plus the inside bend radius.
