The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend.

Calculating bend radius sheet metal.

When bends are made smaller than the required min. Material to the inside of this line ought to compress whereas the material on the outside of it should expand. Bending angles greater than 90 degrees. A is the bending angle in the above equation so.

Cells on the right will output the desired values. Bend radii minimum bend sizes. Therefore the bend allowance added to the flange lengths is equal to the total flat. Sheet metal calculator bend allowance equations and calculator.

Outside setback ossb tangent degree of bend angle 2 inside bend radius material thickness bend deduction bd outside setback 2 bend allowance there are two ways to calculate the flat blank. The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length. Radius of a bend is determined by the hardness and thickness of the metal. Choose a bend radius that matches your minimum bend.

With this free online tool we quickly get the sheet metal bend deduction and therefore the sheet metal blank initial flat length from the finished part measurements. When we calculate the bend allowance we find that it equals 457. As you can see the bend allowance and bend deduction are closely related below. It simply processes these variables through the equations we will discuss below.

Most sheet metal materials will conform to the calculations. Bend allowance is the amount of metal to be added to the total layout. The resulting inside bend radius on the part will remain at 63 percent of material thickness. This page also includes a link to a on line sheet metal bend allowance calculator.

In order to develop the flat pattern we add 457 to 1 625 and 2 625 to arrive at 4 707. You only have to insert interior angle flange lengths k factor inside radius and material thickness. The most important considerations when bending metal is the min. Radius metal will crack at the outside heel of the bend.

To calculate the neutral axis distance from the inner face t we can subtract inside bend radius from r. Punch edge radius in. Determine your minimum bend by measuring the distance from your closest feature i e. And by having t and the sheet thickness t we can calculate the k factor as follow.

The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. A cutout or the edge of your flange to your bend. To calculate r which is the radius of the arc on the neutral axis we can use the following equation. The white dashed line on the part shown above represents the neutral axis which is the theoretical point in the material that does not change during the course of forming.

Below is our simple bend allowance calculator it works by inputing the material thickness bend angle inside radius and k factor.
