Sheet Metal Radius Calculator

Here again a minimum bend radius is not necessarily the same thing as a sharp bend.

Sheet metal radius calculator.

Punch edge radius in. Ultimate tensile strength psi. Sheet metal calculator bend allowance equations and calculator. Discover all our calculation tools in the calculators section of the top menu.

Cells on the right will output the desired values. Die edge radius in. To solve this cmrp provides easy to use measurement calculators. Bend allowance calculator tells you the amount of metal to add.

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. Minimum sheet metal flange bend length 3 x sheet thickness bend radius. Alternatively you can design with.

This change in sheet length depends on the position of neutral axis or k factor. This page also includes a link to a on line sheet metal bend allowance calculator. A sharp bend will always be less than a minimum bend radius but a minimum bend radius does not need to be sharp. Whereas the outer surface is stretched.

Most sheet metal materials will conform to the calculations. It shall be equal to three times of sheet thickness plus bend radius. When sheet metal is bend the inside bending surface is compressed. 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. As a result overall sheet length increases. Best way to calculate k factor in sheet metal is by reverse engineering. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.

Use this document to choose values that are both manufacturable and meet your needs. This calculator predicts what the minimum bend radius should be to avoid chacking or orange peeling on the outside radius of the bend. Minimum sheet metal flange bend length is required to avoid cracks in the bending area.
