Sheet Metal Radius Calculator

Input material thickness and and inner radius to get the data of k factor y factor neutral layer.

Sheet metal radius calculator.

Then input leg length a and b to get the flat size of the sheet. When it comes to curved steel finding the precise measurements is a challenging undertaking. Then input the bend angle to get the arc length bend allowance and bend deduction. Die edge radius in.

Enter k factor values. Use k factor calculator to calculate k factor values. Sheet metal calculator bend allowance equations and calculator. When sheet metal is bend the inside bending surface is compressed.

Alternatively you can design with. Use this document to choose values that are both manufacturable and meet your needs. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. This page also includes a link to a on line sheet metal bend allowance calculator.

To solve this cmrp provides easy to use measurement calculators. A sharp bend will always be less than a minimum bend radius but a minimum bend radius does not need to be sharp. Here are the steps to be followed to calculate sheet metal flat length. Here again a minimum bend radius is not necessarily the same thing as a sharp bend.

Enter flange length internal radius and thickness values. Punch edge radius in. This calculator predicts what the minimum bend radius should be to avoid chacking or orange peeling on the outside radius of the bend. Value of bend deduction and flat pattern are shown in result section.

Sheet metal bending parameters calculator this tool allows you to determine tonnage internal radius v die opening and minimum flange. You just have to insert the characteristics of the sheet metal to be bent. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. As a result overall sheet length increases.

This change in sheet length depends on the position of neutral axis or k factor. Cells on the right will output the desired values. Whereas the outer surface is stretched. Ultimate tensile strength psi.

You only have to insert interior angle flange lengths k factor inside radius and material thickness. Best way to calculate k factor in sheet metal is by reverse engineering.
