Sheet Metal Bend Radius Calculator

Ultimate tensile strength psi.

Sheet metal bend radius calculator.

Most sheet metal materials. Die edge radius in. Bend allowance sheet metal change inlength due to bending operation 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.

Precision sheet metal fabrication request a quote. Bend radii minimum bend sizes. You only have to insert interior angle flange lengths k factor inside radius and material thickness. Material thickness microform bend deduction.

Bend allowance calculator tells you the amount of metal to add. 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. Most sheet metal materials will conform to the calculations.

Online bend deduction calculator. Therefore the bend allowance added to the flange lengths is equal to the total flat. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal.

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. Bend formula example. Punch edge radius in. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend.

Cells on the right will output the desired values. Then input the bend angle to get the arc length bend allowance and bend deduction. Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal. This page also includes a link to a on line sheet metal bend allowance calculator.

You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k. Input material thickness and and inner radius to get the data of k factor y factor neutral layer. Automatically calculate bend deduction bend allowance and k factor for sheet metal fabrication and forming. 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. The material thickness will be measured in decimal form not by the gauge number.
