Calculate Radius Sheet Metal

Then input the bend angle to get the arc length bend allowance and bend deduction.

Calculate radius sheet metal.

Punch edge radius in. And by having t and the sheet thickness t we can calculate the k factor as follow. Bend radii minimum bend sizes. This change in sheet length depends on the position of neutral axis or k factor.

Cells on the right will output the desired values. As a result overall sheet length increases. This calculator predicts what the minimum bend radius should be to avoid chacking or orange peeling on the outside radius of the bend. Determine your minimum bend by measuring the distance from your closest feature i e.

You only have to insert interior angle flange lengths k factor inside radius and material thickness. A is the bending angle in the above equation so. Choose a bend radius that matches your minimum bend. Sheet metal calculator bend allowance equations and calculator.

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. A cutout or the edge of your flange to your bend. To calculate r which is the radius of the arc on the neutral axis we can use the following equation. Then input leg length a and b to get the flat size of the sheet.

Die edge radius in. When sheet metal is bend the inside bending surface is compressed. Here again a minimum bend radius is not necessarily the same thing as a sharp bend. This page also includes a link to a on line sheet metal bend allowance calculator.

Ultimate tensile strength psi. Best way to calculate k factor in sheet metal is by reverse engineering. Whereas the outer surface is stretched. Input material thickness and and inner radius to get the data of k factor y factor neutral layer.

The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal.
