Bend Radius Sheet Metal Table

If you have any questions or want to discuss your design contact us.

Bend radius sheet metal table.

This punch and die set would be mounted in a press. 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. We are here to help.

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. Steel american iron and steel institute. If these guidelines are not followed more research and or some form of analysis may be requried. Thus the smallest radius of any bend in a sheet should be at least equal to the thickness of the sheet.

A section view of a typical punch and die set used to create sheet metal bends. Another important consideration. A cutout or the edge of your flange to your bend. The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance.

Figure 2 shows us a typical punch and die set used to bend sheet metal. Sheet metal bend radii. Below is xometry s minimum bend radius reference table which is based on theoretical sheet metal gauge thicknesses. You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k.

Where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t. Choose a bend radius that matches your minimum bend. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. When the proportional limits of a specific material are reached or exceeded the material remains bent figure one.

Springback and inside radius calculator for sheet metal. To use the tables below. Preferred recommended 90 degree bend radii for various sheet metals. For example if the thickness of the sheet is 1 mm the minimum bend radius should be 1 mm.

It is possible to choose other bends if you require but additional lead time and tooling charges may apply. Determine your minimum bend by measuring the distance from your closest feature i e. 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.
