Bend Radius Sheet Metal Table

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

Bend radius sheet metal table.

A section view of a typical punch and die set used to create sheet metal bends. When the sheet metal is bent a bend radius is required at the bend. You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k. Bending is one of the most common sheet metal fabrication operations.

L 26 26 50 50. Visit our learning library which features all of our training courses and tutorials at http. It is possible to choose other bends if you require but additional lead time and tooling charges may apply. The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance.

Figure 1 31 the 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 radii listed are standard minimum if manufacturing for aircraft and aerospace applications. Sheet metal bend radius.

The minimum bend radius data shown in these charts is measured to the inside of the bend. Table 1 preferred recommended 90 degree bend radii for various sheet metals. This is done through the application of force on a workpiece. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.

Bend radii minimum bend sizes. Sheet metal bend radii if these guidelines are not followed more research and or some form of analysis may be requried. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. Exemple 1 for metal sheet bending tables.

Use this document to choose values that are both manufacturable and meet your needs. The bend radius refer to table 1 9. The second important number when creating sheet metal designs is the bend radius value. Table 1 14 minimum distance from the long round hole to the bend edge.

Want all of our free solidworks sheet metal training videos. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. 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.
