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. When sheet metal makes a transition from a bend to a flat surface or to another bend it tends to rip and tear. Depending on the types of parts that you design you may have to create additional sheet metal features. Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured.

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. Bends in sheet metal are manufactured using sheet metal brakes. Figure 3 figure 4 figure 5 figure 6. The resulting model faces are all nicely trimmed and all have appropriate corner relief in the flat pattern.

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. In general a minimum bend relief is equal to the material thickness plus the inside bend radius. To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend. Relief helps to control sheet metal material behavior and to prevent unwanted deformation during unbend operations.
