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.

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

Where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t. Figure 2 shows us a typical punch and die set used to bend sheet metal. A section view of a typical punch and die set used to create sheet metal bends. 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. The material thickness will be measured in decimal form not by the gauge number. Thus the smallest radius of any bend in a sheet should be at least equal to the thickness of the sheet. 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. 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. For example if the thickness of the sheet is 1 mm the minimum bend radius should be 1 mm.

To use the tables below. Another important consideration. The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance. To keep it simple i also use a 2 mm inside radius.

Below is xometry s minimum bend radius reference table which is based on theoretical sheet metal gauge thicknesses. A cutout or the edge of your flange to your bend. Determine your minimum bend by measuring the distance from your closest feature i e. Springback and inside radius calculator for sheet metal.

Preferred recommended 90 degree bend radii for various sheet metals. Sheet metal bend radii. We are here to help.
