Sheet metal bend radius calculator.

Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal. Then input the bend angle to get the arc length bend allowance and bend deduction. 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. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal.

Online bend deduction calculator. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. This page also includes a link to a on line sheet metal bend allowance calculator. Bend allowance sheet metal change inlength due to bending operation calculator.

Cells on the right will output the desired values. The most important consideration when bending metal on a brake is the minimum bend radius. Bend radii minimum bend sizes. Use this document to choose values that are both manufacturable and meet your needs.

Inside bend radius r inches must be greater than 90 and less than 180 degrees. Punch edge radius in. The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance. You only have to insert interior angle flange lengths k factor inside radius and material thickness.

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

Then input leg length a and b to get the flat size of the sheet. 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. Material thickness microform bend deduction.

Therefore the bend allowance added to the flange lengths is equal to the total flat. Most sheet metal materials. Sheet metal calculator bend allowance equations and calculator. The material thickness will be measured in decimal form not by the gauge number.

Most sheet metal materials will conform to the calculations. Automatically calculate bend deduction bend allowance and k factor for sheet metal fabrication and forming.
