Bend Radius Sheet Metal Table

This springback and inside radius calculator estimates the amount of angular change and the relaxing of bend radius that occurs when metal is bent and released from pressure.

Bend radius sheet metal table.

The material thickness will be measured in decimal form not by the gauge number. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. The bend radius of a sheet metal design will be based on the wall thickness of the part and the tooling that is available in house. Determine your minimum bend by measuring the distance from your closest feature i e.

To keep it simple i also use a 2 mm inside radius. Let s say i have a 2 mm thick sheet and i want to bend it. Steel american iron and steel institute. It is possible to choose other bends if you require but additional lead time and tooling charges may apply.

Choose a bend radius that matches your minimum bend. This punch and die set would be mounted in a press. When the proportional limits of a specific material are reached or exceeded the material remains bent figure one. Figure 2 shows us a typical punch and die set used to bend sheet metal.

The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance. A cutout or the edge of your flange to your bend. To use the tables below. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase.

If you have any questions or want to discuss your design contact us. Preferred recommended 90 degree bend radii for various sheet metals. Sheet metal bend radii. Another important consideration.

Where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t. Below is xometry s minimum bend radius reference table which is based on theoretical sheet metal gauge thicknesses. I can now see that the minimum flange length is 8 5 mm for such a bend so i have to keep it in mind when designing. For example if the thickness of the sheet is 1 mm the minimum bend radius should be 1 mm.

Springback and inside radius calculator for sheet metal. We are here to help. You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k.
