Sheet Metal Radius Calculator

Use this document to choose values that are both manufacturable and meet your needs.

Sheet metal radius calculator. Sheet metal bending parameters calculator this tool allows you to determine tonnage internal radius v die opening and minimum flange. Alternatively you can design with. This calculator predicts what the minimum bend radius should be to avoid chacking or orange peeling on the outside radius of the bend. Enter flange length internal radius and thickness values.

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. Here are the steps to be followed to calculate sheet metal flat length. Then input the bend angle to get the arc length bend allowance and bend deduction.

When sheet metal is bend the inside bending surface is compressed. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. This page also includes a link to a on line sheet metal bend allowance calculator. Most sheet metal materials will conform to the calculations.

You only have to insert interior angle flange lengths k factor inside radius and material thickness. As a result overall sheet length increases. Then input leg length a and b to get the flat size of the sheet. Input material thickness and and inner radius to get the data of k factor y factor neutral layer.

Whereas the outer surface is stretched. Value of bend deduction and flat pattern are shown in result section. A sharp bend will always be less than a minimum bend radius but a minimum bend radius does not need to be sharp. 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. Ultimate tensile strength psi. This change in sheet length depends on the position of neutral axis or k factor. Die edge radius in.

When it comes to curved steel finding the precise measurements is a challenging undertaking. To solve this cmrp provides easy to use measurement calculators. Use k factor calculator to calculate k factor values. Best way to calculate k factor in sheet metal is by reverse engineering.

Cells on the right will output the desired values. Keep default values in calculator as zero.
