Sheet metal bend radius.
Bend radius sheet metal table.
The second important number when creating sheet metal designs is the bend radius value.
Use this document to choose values that are both manufacturable and meet your needs.
Bending is one of the most common sheet metal fabrication operations.
The minimum bend radius data shown in these charts is measured to the inside of the bend.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
Table 1 preferred recommended 90 degree bend radii for various sheet metals.
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.
The force must exceed the material s yield strength to achieve a plastic deformation.
L 26 26 50 50.
The bend radius refer to table 1 9.
You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k.
Sheet metal bend radii if these guidelines are not followed more research and or some form of analysis may be requried.
We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.
The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase.
It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.
Table 1 14 minimum distance from the long round hole to the bend edge.
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.
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.
Want all of our free solidworks sheet metal training videos.
When the sheet metal is bent a bend radius is required at the bend.
Figure 1 31 the minimum distance from the long round hole to the bend edge.
Bend radii minimum bend sizes.
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.
The material thickness will be measured in decimal form not by the gauge number.
This is done through the application of force on a workpiece.
