Sheet Metal Radius Calculator

This calculator predicts what the minimum bend radius should be to avoid chacking or orange peeling on the outside radius of the bend.

Sheet metal radius calculator.

Alternatively you can design with. You just have to insert the characteristics of the sheet metal to be bent. Use k factor calculator to calculate k factor values. Here are the steps to be followed to calculate sheet metal flat length.

Cells on the right will output the desired values. When it comes to curved steel finding the precise measurements is a challenging undertaking. Enter flange length internal radius and thickness values. When sheet metal is bend the inside bending surface is compressed.

Value of bend deduction and flat pattern are shown in result section. Then input leg length a and b to get the flat size of the sheet. 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. Here again a minimum bend radius is not necessarily the same thing as a sharp bend.

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

You only have to insert interior angle flange lengths k factor inside radius and material thickness. To solve this cmrp provides easy to use measurement calculators. Whereas the outer surface is stretched. Die edge radius in.

As a result overall sheet length increases. Ultimate tensile strength psi. Input material thickness and and inner radius to get the data of k factor y factor neutral layer. Then input the bend angle to get the arc length bend allowance and bend deduction.

Punch edge radius in. Best way to calculate k factor in sheet metal is by reverse engineering. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. A sharp bend will always be less than a minimum bend radius but a minimum bend radius does not need to be sharp.

Enter k factor values. Use this document to choose values that are both manufacturable and meet your needs.
