Sheet metal corner relief design.

When you add relief sheet metal sections are removed from the model. Bends in sheet metal are manufactured using sheet metal brakes. In general a minimum bend relief is equal to the material thickness plus the inside bend radius. To create a relief locally you can select one or two hard edges one or two bends or a bend and a hard edge.

A 1 degree tolerance on all bend angles. Click corner relief sheet metal toolbar. To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend. You can apply corner relief automatically to all corners or manually to individual sets of corners.

The resulting model faces are all nicely trimmed and all have appropriate corner relief in the flat pattern. The selected items can be a 3d solid with sheet metal features a face or a hard edge of the solid. There are two things that can be done to reduce the risk of sheet metal tearing. Bend relief is provided at the end of bending edge in sheet metal design to avoid any crack tearing in the corner.

Click insert sheet metal corner relief. Relief height is generally kept greater than two times of sheet thickness plus bend radius. If it is ok for the metal to rip the minimum bend relief is zero. If a 3d solid is selected the command recognizes the places where corner or bend reliefs are needed and creates them automatically.

One benefit of a bend relief is that it makes the part easier to produce. First utilize minimal bend radius of internal bend radius equal to material thickness. Understanding corner relief design flexibility2 the contour flange is created using the auto miter option and the seven edge loop of the polygon is selected. To open the corner relief propertymanager.

You should also incorporate the use of bend relief cuts with a thickness of at least the thickness of the material with strong preference for bend relief cuts of a thickness equal to material thickness plus 1 64 inches. Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured. Depending on the types of parts that you design you may have to create additional sheet metal features. Extrude hole size position guidelines creating an extruded hole using a punching process requires extreme pressure force.

Use the corner relief propertymanager to apply corner treatments to a folded sheet metal body that persist in the flattened state. Figure 3 figure 4 figure 5 figure 6.
