Sheet Metal Radius Calculator

Die edge radius in.

Sheet metal radius calculator.

Discover all our calculation tools in the calculators section of the top menu. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. 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. It shall be equal to three times of sheet thickness plus bend radius.

When sheet metal is bend the inside bending surface is compressed. This calculator predicts what the minimum bend radius should be to avoid chacking or orange peeling on the outside radius of the bend. Use this document to choose values that are both manufacturable and meet your needs. Alternatively you can design with.

Here again a minimum bend radius is not necessarily the same thing as a sharp bend. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. As a result overall sheet length increases. Minimum sheet metal flange bend length is required to avoid cracks in the bending area.

This page also includes a link to a on line sheet metal bend allowance calculator. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. The most important consideration when bending metal on a brake is the minimum bend radius. Bend allowance calculator tells you the amount of metal to add.

Most sheet metal materials will conform to the calculations. Cells on the right will output the desired values. You only have to insert interior angle flange lengths k factor inside radius and material thickness. Best way to calculate k factor in sheet metal is by reverse engineering.

This change in sheet length depends on the position of neutral axis or k factor. 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. 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.

Punch edge radius in. Ultimate tensile strength psi. To solve this cmrp provides easy to use measurement calculators.
