Sheet Metal Corner Relief Design

Depending on the types of parts that you design you may have to create additional sheet metal features.

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. A 1 degree tolerance on all bend angles. When sheet metal makes a transition from a bend to a flat surface or to another bend it tends to rip and tear. Bend relief is provided at the end of bending edge in sheet metal design to avoid any crack tearing in the corner.

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. To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend. Bends in sheet metal are manufactured using sheet metal brakes.

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. Figure 3 figure 4 figure 5 figure 6.
