Sheet Metal Radius Calculator

Enter flange length internal radius and thickness values.

Sheet metal radius calculator.

When it comes to curved steel finding the precise measurements is a challenging undertaking. Sheet metal calculator bend allowance equations and calculator. Best way to calculate k factor in sheet metal is by reverse engineering. Keep default values in calculator as zero.

Then input the bend angle to get the arc length bend allowance and bend deduction. This calculator predicts what the minimum bend radius should be to avoid chacking or orange peeling on the outside radius of the bend. Input material thickness and and inner radius to get the data of k factor y factor neutral layer. This page also includes a link to a on line sheet metal bend allowance calculator.

Here again a minimum bend radius is not necessarily the same thing as a sharp bend. Use this document to choose values that are both manufacturable and meet your needs. A sharp bend will always be less than a minimum bend radius but a minimum bend radius does not need to be sharp. Punch edge radius in.

It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Cells on the right will output the desired values. Value of bend deduction and flat pattern are shown in result section. To solve this cmrp provides easy to use measurement calculators.

You just have to insert the characteristics of the sheet metal to be bent. Use k factor calculator to calculate k factor values. 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.

Most sheet metal materials will conform to the calculations. Then input leg length a and b to get the flat size of the sheet. When sheet metal is bend the inside bending surface is compressed. This change in sheet length depends on the position of neutral axis or k factor.

Die edge radius in. As a result overall sheet length increases. Here are the steps to be followed to calculate sheet metal flat length. Enter k factor values.

Whereas the outer surface is stretched. Ultimate tensile strength psi.
