Table 1 14 minimum distance from the long round hole to the bend edge.
Bend radius sheet metal table.
Table 1 preferred recommended 90 degree bend radii for various sheet metals.
The minimum bend radius data shown in these charts is measured to the inside of the bend.
Bending is one of the most common sheet metal fabrication operations.
You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k.
The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase.
Since commercial sheet metal bending can be done with less concern for stresses caused during forming operation the radius can be near zero for thin sheet metal.
L 26 26 50 50.
The bend radius refer to table 1 9.
It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.
The force must exceed the material s yield strength to achieve a plastic deformation.
We have a metal sheet of 3 m m thickness in iron with a hardness of 42 48kg mm2 if we go to the top of the table we see the thicknesses in brown we look at the 3 thickness of the sheet and we go down to the blue box we see a value of 240 this is in kn mm2 and if we take a 0 it will be in ton.
Figure 1 31 the minimum distance from the long round hole to the bend edge.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
A section view of a typical punch and die set used to create sheet metal bends.
This is done through the application of force on a workpiece.
The second important number when creating sheet metal designs is the bend radius value.

The material thickness will be measured in decimal form not by the gauge number.
Exemple 1 for metal sheet bending tables.
Use this document to choose values that are both manufacturable and meet your needs.
Bend radii minimum bend sizes.
Sheet metal bend radius.
Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.
It is possible to choose other bends if you require but additional lead time and tooling charges may apply.
Sheet metal bend radii if these guidelines are not followed more research and or some form of analysis may be requried.
When the sheet metal is bent a bend radius is required at the bend.
We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.
