Sheet Metal Radius Calculator

It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.

Sheet metal radius calculator.

Sheet metal calculator bend allowance equations and calculator. Die edge radius in. A is the bending angle in the above equation so. Discover all our calculation tools in the calculators section of the top menu.

Bend allowance calculator tells you the amount of metal to add. Most sheet metal materials will conform to the calculations. A sharp bend will always be less than a minimum bend radius but a minimum bend radius does not need to be sharp. Cells on the right will output the desired values.

This tool allows you to determine tonnage internal radius v die opening and minimum flange you just have to insert the characteristics of the sheet metal to be bent. Alternatively you can design with. 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. Here again a minimum bend radius is not necessarily the same thing as a sharp bend.

Punch edge radius in. Whereas the outer surface is stretched. This calculator predicts what the minimum bend radius should be to avoid chacking or orange peeling on the outside radius of the bend. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend.

To calculate r which is the radius of the arc on the neutral axis we can use the following equation. Use this document to choose values that are both manufacturable and meet your needs. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. Bend allowance 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.

As a result overall sheet length increases. When sheet metal is bend the inside bending surface is compressed. To calculate the neutral axis distance from the inner face t we can subtract inside bend radius from r. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal.

And by having t and the sheet thickness t we can calculate the k factor as follow. You only have to insert interior angle flange lengths k factor inside radius and material thickness. This page also includes a link to a on line sheet metal bend allowance calculator. Best way to calculate k factor in sheet metal is by reverse engineering.
