Bend Radius Sheet Metal Table

The material thickness will be measured in decimal form not by the gauge number.

Bend radius sheet metal table.

It is possible to choose other bends if you require but additional lead time and tooling charges may apply. A cutout or the edge of your flange to your bend. Preferred recommended 90 degree bend radii for various sheet metals. To keep it simple i also use a 2 mm inside radius.

If these guidelines are not followed more research and or some form of analysis may be requried. To use the tables below. Steel american iron and steel institute. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.

For example if the thickness of the sheet is 1 mm the minimum bend radius should be 1 mm. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. Sheet metal bend radii. Choose a bend radius that matches your minimum bend.

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. Determine your minimum bend by measuring the distance from your closest feature i e. We are here to help.

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. This punch and die set would be mounted in a press. Springback and inside radius calculator for sheet metal. Thus the smallest radius of any bend in a sheet should be at least equal to the thickness of the sheet.

When the proportional limits of a specific material are reached or exceeded the material remains bent figure one. Below is xometry s minimum bend radius reference table which is based on theoretical sheet metal gauge thicknesses. The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance. Where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t.

You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k. 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. If you have any questions or want to discuss your design contact us.
