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

Sheet metal bend radius calculator.

Precision sheet metal fabrication request a quote. Bend allowance calculator tells you the amount of metal to add. Ultimate tensile strength psi. Most sheet metal materials.

You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k. Bend formula example. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend. Die edge radius in.

Then input the bend angle to get the arc length bend allowance and bend deduction. Bend allowance sheet metal change inlength due to bending operation calculator. The most important consideration when bending metal on a brake is the minimum bend radius. Microform precision llc 4244 south market.

The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. You only have to insert interior angle flange lengths k factor inside radius and material thickness. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Online bend deduction calculator.

Bend radii minimum bend sizes. Inside bend radius r inches must be greater than 90 and less than 180 degrees. Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal. Sheet metal calculator bend allowance equations and calculator.

The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length. Input material thickness and and inner radius to get the data of k factor y factor neutral layer. Punch edge radius in. Therefore the bend allowance added to the flange lengths is equal to the total flat.

The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance. Then input leg length a and b to get the flat size of the sheet. This page also includes a link to a on line sheet metal bend allowance calculator. Most sheet metal materials will conform to the calculations.

Automatically calculate bend deduction bend allowance and k factor for sheet metal fabrication and forming. 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.
