Sheet Metal Radius Calculator

Ultimate tensile strength psi.

Sheet metal radius calculator.

Punch edge radius in. A sharp bend will always be less than a minimum bend radius but a minimum bend radius does not need to be sharp. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. Sheet metal calculator bend allowance equations and calculator.

Most sheet metal materials will conform to the calculations. Cells on the right will output the desired values. Use this document to choose values that are both manufacturable and meet your needs. A is the bending angle in the above equation so.

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. As a result overall sheet length increases. And by having t and the sheet thickness t we can calculate the k factor as follow. This calculator predicts what the minimum bend radius should be to avoid chacking or orange peeling on the outside radius of the bend.

You only have to insert interior angle flange lengths k factor inside radius and material thickness. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. Die edge radius in. Whereas the outer surface is stretched.

When sheet metal is bend the inside bending surface is compressed. Alternatively you can design with. This change in sheet length depends on the position of neutral axis or k factor. Bend allowance calculator tells you the amount of metal to add.

Best way to calculate k factor in sheet metal is by reverse engineering. 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. To calculate r which is the radius of the arc on the neutral axis we can use the following equation. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend.

This page also includes a link to a on line sheet metal bend allowance calculator. Here again a minimum bend radius is not necessarily the same thing as a sharp bend. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. The most important consideration when bending metal on a brake is the minimum bend radius.
