Sheet Metal Radius Calculator

Enter k factor values.

Sheet metal radius calculator.

You just have to insert the characteristics of the sheet metal to be bent. Keep default values in calculator as zero. 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.

To solve this cmrp provides easy to use measurement calculators. Sheet metal calculator bend allowance equations and calculator. Cells on the right will output the desired values. This page also includes a link to a on line sheet metal bend allowance calculator.

It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Die edge radius in. You only have to insert interior angle flange lengths k factor inside radius and material thickness. 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. A sharp bend will always be less than a minimum bend radius but a minimum bend radius does not need to be sharp. Use this document to choose values that are both manufacturable and meet your needs. Then input the bend angle to get the arc length bend allowance and bend deduction.

Here again a minimum bend radius is not necessarily the same thing as a sharp bend. When sheet metal is bend the inside bending surface is compressed. 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.

Use k factor calculator to calculate k factor values. Here are the steps to be followed to calculate sheet metal flat length. Input material thickness and and inner radius to get the data of k factor y factor neutral layer. Value of bend deduction and flat pattern are shown in result section.

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 change in sheet length depends on the position of neutral axis or k factor. Whereas the outer surface is stretched.

The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. As a result overall sheet length increases.
