Bend Radius Sheet Metal Table

You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k.

Bend radius sheet metal table.

To keep it simple i also use a 2 mm inside radius. Another important consideration. Preferred recommended 90 degree bend radii for various sheet metals. Thus the smallest radius of any bend in a sheet should be at least equal to the thickness of the sheet.

If these guidelines are not followed more research and or some form of analysis may be requried. A cutout or the edge of your flange to your bend. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. It is possible to choose other bends if you require but additional lead time and tooling charges may apply.

Steel american iron and steel institute. Where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t. To use the tables below. When the proportional limits of a specific material are reached or exceeded the material remains bent figure one.

The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance. If you have any questions or want to discuss your design contact us. A section view of a typical punch and die set used to create sheet metal bends. This punch and die set would be mounted in a press.

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. For example if the thickness of the sheet is 1 mm the minimum bend radius should be 1 mm. Sheet metal bend radii. Let s say i have a 2 mm thick sheet and i want to bend it.

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. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. 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. Springback and inside radius calculator for sheet metal.

Choose a bend radius that matches your minimum bend. We are here to help. The material thickness will be measured in decimal form not by the gauge number.
