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. Punch edge radius in. As a result overall sheet length increases. Die edge radius in. Best way to calculate k factor in sheet metal is by reverse engineering.

Sheet metal bending parameters calculator this tool allows you to determine tonnage internal radius v die opening and minimum flange. 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. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.

This change in sheet length depends on the position of neutral axis or k factor. To solve this cmrp provides easy to use measurement calculators. Ultimate tensile strength psi. When it comes to curved steel finding the precise measurements is a challenging undertaking.

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. Enter flange length internal radius and thickness values. Cells on the right will output the desired values.

Keep default values in calculator as zero. Use this document to choose values that are both manufacturable and meet your needs. Enter k factor values. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal.

When sheet metal is bend the inside bending surface is compressed. You only have to insert interior angle flange lengths k factor inside radius and material thickness. Use k factor calculator to calculate k factor values. Then input leg length a and b to get the flat size of the sheet.

A sharp bend will always be less than a minimum bend radius but a minimum bend radius does not need to be sharp. Here again a minimum bend radius is not necessarily the same thing as a sharp bend. Sheet metal calculator bend allowance equations and calculator. This page also includes a link to a on line sheet metal bend allowance calculator.

Whereas the outer surface is stretched. Alternatively you can design with.
