Sheet Metal Bend Radius Calculator

Inside bend radius r inches must be greater than 90 and less than 180 degrees.

Sheet metal bend radius calculator.

The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend. Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal. You only have to insert interior angle flange lengths k factor inside radius and material thickness. Then input leg length a and b to get the flat size of the sheet.

Then input the bend angle to get the arc length bend allowance and bend deduction. Automatically calculate bend deduction bend allowance and k factor for sheet metal fabrication and forming. 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.

Material thickness microform bend deduction. Ultimate tensile strength psi. Precision sheet metal fabrication request a quote. Use this document to choose values that are both manufacturable and meet your needs.

The most important consideration when bending metal on a brake is the minimum bend radius. Bend formula example. Input material thickness and and inner radius to get the data of k factor y factor neutral layer. Bend allowance sheet metal change inlength due to bending operation calculator.

Cells on the right will output the desired values. You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k. Die edge radius in. Therefore the bend allowance added to the flange lengths is equal to the total flat.

The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length. Most sheet metal materials will conform to the calculations. Punch edge radius in. 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 material thickness will be measured in decimal form not by the gauge number. Bend allowance calculator tells you the amount of metal to add. Online bend deduction calculator. Bend radii minimum bend sizes.
