Sheet Metal Radius Calculator

Minimum sheet metal flange bend length is required to avoid cracks in the bending area.

Sheet metal radius calculator.

Sheet metal calculator bend allowance equations and calculator. This change in sheet length depends on the position of neutral axis or k factor. 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.

It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. It shall be equal to three times of sheet thickness plus bend radius. When it comes to curved steel finding the precise measurements is a challenging undertaking. Best way to calculate k factor in sheet metal is by reverse engineering.

Die edge radius in. Discover all our calculation tools in the calculators section of the top menu. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. 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.

This page also includes a link to a on line sheet metal bend allowance calculator. Alternatively you can design with. As a result overall sheet length increases. Use this document to choose values that are both manufacturable and meet your needs.

Ultimate tensile strength psi. 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. 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. Here again a minimum bend radius is not necessarily the same thing as a sharp bend. Punch edge radius in. Minimum sheet metal flange bend length 3 x sheet thickness bend radius.

Cells on the right will output the desired values. When sheet metal is bend the inside bending surface is compressed. To solve this cmrp provides easy to use measurement calculators.
