Sheet Metal Radius 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.

Sheet metal radius calculator.

Alternatively you can design with. Most sheet metal materials will conform to the calculations. Die edge radius in. Sheet metal calculator bend allowance equations and calculator.

When sheet metal is bend the inside bending surface is compressed. Here again a minimum bend radius is not necessarily the same thing as a sharp bend. Whereas the outer surface is stretched. This page also includes a link to a on line sheet metal bend allowance calculator.

As a result overall sheet length increases. Enter k factor values. Use this document to choose values that are both manufacturable and meet your needs. Keep default values in calculator as zero.

Input material thickness and and inner radius to get the data of k factor y factor neutral layer. This calculator predicts what the minimum bend radius should be to avoid chacking or orange peeling on the outside radius of the bend. A sharp bend will always be less than a minimum bend radius but a minimum bend radius does not need to be sharp. Enter flange length internal radius and thickness values.

The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. To solve this cmrp provides easy to use measurement calculators. Ultimate tensile strength psi. This change in sheet length depends on the position of neutral axis or k factor.

When it comes to curved steel finding the precise measurements is a challenging undertaking. Best way to calculate k factor in sheet metal is by reverse engineering. You just have to insert the characteristics of the sheet metal to be bent. Sheet metal bending parameters calculator this tool allows you to determine tonnage internal radius v die opening and minimum flange.

Then input leg length a and b to get the flat size of the sheet. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Value of bend deduction and flat pattern are shown in result section. Cells on the right will output the desired values.

Then input the bend angle to get the arc length bend allowance and bend deduction. Punch edge radius in.
