Sheet Metal Bend Radius Calculator

You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k.

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. Bend allowance calculator tells you the amount of metal to add. 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. Therefore the bend allowance added to the flange lengths is equal to the total flat.

Then input the bend angle to get the arc length bend allowance and bend deduction. Ultimate tensile strength psi. Most sheet metal materials will conform to the calculations. You only have to insert interior angle flange lengths k factor inside radius and material thickness.

Precision sheet metal fabrication request a quote. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Use this document to choose values that are both manufacturable and meet your needs. Punch edge radius in.

Die edge radius in. Cells on the right will output the desired values. The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length. Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal.

Bend radii minimum bend sizes. The material thickness will be measured in decimal form not by the gauge number. The most important consideration when bending metal on a brake is the minimum bend radius. The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance.

Bend formula example. Inside bend radius r inches must be greater than 90 and less than 180 degrees. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. Bend allowance sheet metal change inlength due to bending operation calculator.

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. Most sheet metal materials. Online bend deduction calculator.
