Calculate Radius Sheet Metal

A cutout or the edge of your flange to your bend.

Calculate radius sheet metal.

You only have to insert interior angle flange lengths k factor inside radius and material thickness. Input material thickness and and inner radius to get the data of k factor y factor neutral layer. Here again a minimum bend radius is not necessarily the same thing as a sharp bend. And by having t and the sheet thickness t we can calculate the k factor as follow.

Sheet metal calculator bend allowance equations and calculator. Most sheet metal materials will conform to the calculations. Bend radii minimum bend sizes. This page also includes a link to a on line sheet metal bend allowance calculator.

When sheet metal is bend the inside bending surface is compressed. Whereas the outer surface is stretched. Die edge radius in. Choose a bend radius that matches your minimum bend.

Best way to calculate k factor in sheet metal is by reverse engineering. A sharp bend will always be less than a minimum bend radius but a minimum bend radius does not need to be sharp. Then input leg length a and b to get the flat size of the sheet. To calculate the neutral axis distance from the inner face t we can subtract inside bend radius from r.

This calculator predicts what the minimum bend radius should be to avoid chacking or orange peeling on the outside radius of the bend. 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. To calculate r which is the radius of the arc on the neutral axis we can use the following equation.

Then input the bend angle to get the arc length bend allowance and bend deduction. As a result overall sheet length increases. Punch edge radius in. This change in sheet length depends on the position of neutral axis or k factor.

A is the bending angle in the above equation so.
