Sheet Metal Radius Calculator

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

Sheet metal radius calculator.

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 change in sheet length depends on the position of neutral axis or k factor. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. Bend allowance calculator tells you the amount of metal to add.

Most sheet metal materials will conform to the calculations. To solve this cmrp provides easy to use measurement calculators. 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.

Whereas the outer surface is stretched. 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. Best way to calculate k factor in sheet metal is by reverse engineering.

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. You only have to insert interior angle flange lengths k factor inside radius and material thickness. Discover all our calculation tools in the calculators section of the top menu. When sheet metal is bend the inside bending surface is compressed.

When it comes to curved steel finding the precise measurements is a challenging undertaking. Punch edge radius in. It shall be equal to three times of sheet thickness plus bend radius. Sheet metal calculator bend allowance equations and calculator.

This page also includes a link to a on line sheet metal bend allowance calculator. Minimum sheet metal flange bend length 3 x sheet thickness bend radius. As a result overall sheet length increases. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.

Here again a minimum bend radius is not necessarily the same thing as a sharp bend. Cells on the right will output the desired values. Use this document to choose values that are both manufacturable and meet your needs.
