Sheet Metal Radius Calculator

You only have to insert interior angle flange lengths k factor inside radius and material thickness.

Sheet metal 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. Best way to calculate k factor in sheet metal is by reverse engineering. 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.

This page also includes a link to a on line sheet metal bend allowance calculator. Die edge radius in. Most sheet metal materials will conform to the calculations. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.

Ultimate tensile strength psi. 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. Alternatively you can design with. Use this document to choose values that are both manufacturable and meet your needs.

The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. Here again a minimum bend radius is not necessarily the same thing as a sharp bend. As a result overall sheet length increases. Bend allowance calculator tells you the amount of metal to add.

Cells on the right will output the desired values. And by having t and the sheet thickness t we can calculate the k factor as follow. 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. This change in sheet length depends on the position of neutral axis or k factor.

It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. This calculator predicts what the minimum bend radius should be to avoid chacking or orange peeling on the outside radius of the bend. Sheet metal calculator bend allowance equations and calculator. A is the bending angle in the above equation so.

The most important consideration when bending metal on a brake is the minimum bend radius. 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. Punch edge radius in. Whereas the outer surface is stretched.
