Sheet Metal Radius Calculator

Then input leg length a and b to get the flat size of the sheet.

Sheet metal radius calculator.

Value of bend deduction and flat pattern are shown in result section. 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. 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.

Use k factor calculator to calculate k factor values. Sheet metal bending parameters calculator this tool allows you to determine tonnage internal radius v die opening and minimum flange. This change in sheet length depends on the position of neutral axis or k factor. You only have to insert interior angle flange lengths k factor inside radius and material thickness.

Enter flange length internal radius and thickness values. Enter k factor values. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. 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. A sharp bend will always be less than a minimum bend radius but a minimum bend radius does not need to be sharp. Then input the bend angle to get the arc length bend allowance and bend deduction. Here again a minimum bend radius is not necessarily the same thing as a sharp bend.

As a result overall sheet length increases. Alternatively you can design with. You just have to insert the characteristics of the sheet metal to be bent. To solve this cmrp provides easy to use measurement calculators.

Use this document to choose values that are both manufacturable and meet your needs. Whereas the outer surface is stretched. Keep default values in calculator as zero. Die edge radius in.

Best way to calculate k factor in sheet metal is by reverse engineering. Ultimate tensile strength psi. Punch edge radius in. Sheet metal calculator bend allowance equations and calculator.

Most sheet metal materials will conform to the calculations. Here are the steps to be followed to calculate sheet metal flat length.
