Sheet Metal Radius Calculator

The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.

Sheet metal radius calculator.

This calculator predicts what the minimum bend radius should be to avoid chacking or orange peeling on the outside radius of the bend. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. You only have to insert interior angle flange lengths k factor inside radius and material thickness. Punch edge radius in.

Cells on the right will output the desired values. Best way to calculate k factor in sheet metal is by reverse engineering. When it comes to curved steel finding the precise measurements is a challenging undertaking. 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.

Discover all our calculation tools in the calculators section of the top menu. When sheet metal is bend the inside bending surface is compressed. Minimum sheet metal flange bend length is required to avoid cracks in the bending area. To solve this cmrp provides easy to use measurement calculators.

Use this document to choose values that are both manufacturable and meet your needs. Die 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. Most sheet metal materials will conform to the calculations.

Whereas the outer surface is stretched. The most important consideration when bending metal on a brake is the minimum bend radius. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Bend allowance calculator tells you the amount of metal to add.

Sheet metal calculator bend allowance equations and calculator. 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. It shall be equal to three times of sheet thickness plus bend radius. Here again a minimum bend radius is not necessarily the same thing as a sharp bend.

Alternatively you can design with. As a result overall sheet length increases. This page also includes a link to a on line sheet metal bend allowance calculator.
