Therefore the bend allowance added to the flange lengths is equal to the total flat length.

Calculating bend allowance for sheet metal.

Where ba is bending allowance. Sheet metal calculator bend allowance equations and calculator. The most important considerations when bending metal is the min. The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length.

Bend allowance is the amount of metal to be added to the total layout. The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance. Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal. To calculate the neutral axis distance from the inner face t we can subtract inside bend radius from r.

To calculate r which is the radius of the arc on the neutral axis we can use the following equation. When bends are made smaller than the required min. You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k. This page also includes a link to a on line sheet metal bend allowance calculator.

Now that we have both leg length 1 and 2 we can use the following equation again to calculate the bend allowance. Most sheet metal materials will conform to the calculations. The material thickness will be measured in decimal form not by the gauge number. Radius of a bend is determined by the hardness and thickness of the metal.

Radius metal will crack at the outside heel of the bend. And by having t and the sheet thickness t we can calculate the k factor as follow. A is the bending angle in the above equation so. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend.
