Sheet Metal Radius Calculator

Then input the bend angle to get the arc length bend allowance and bend deduction.

Sheet metal radius calculator.

Die edge radius in. 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. Most sheet metal materials will conform to the calculations. You just have to insert the characteristics of the sheet metal to be bent.

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. Sheet metal calculator bend allowance equations and calculator. Enter flange length internal radius and thickness values.

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. Here again a minimum bend radius is not necessarily the same thing as a sharp bend. Enter k factor values.

Input material thickness and and inner radius to get the data of k factor y factor neutral layer. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Use k factor calculator to calculate k factor values. Ultimate tensile strength psi.

Cells on the right will output the desired values. Whereas the outer surface is stretched. 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.

Punch edge radius in. When it comes to curved steel finding the precise measurements is a challenging undertaking. Here are the steps to be followed to calculate sheet metal flat length. 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. Alternatively you can design with. Sheet metal bending parameters calculator this tool allows you to determine tonnage internal radius v die opening and minimum flange. Keep default values in calculator as zero.

This page also includes a link to a on line sheet metal bend allowance calculator. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal.
