Punch edge radius in.
Sheet metal radius calculator.
You just have to insert the characteristics of the sheet metal to be bent.
Here are the steps to be followed to calculate sheet metal flat length.
When sheet metal is bend the inside bending surface is compressed.
This change in sheet length depends on the position of neutral axis or k factor.
Value of bend deduction and flat pattern are shown in result section.
This calculator predicts what the minimum bend radius should be to avoid chacking or orange peeling on the outside radius of the bend.
Keep default values in calculator as zero.
Cells on the right will output the desired values.
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.
Then input leg length a and b to get the flat size of the sheet.
Here again a minimum bend radius is not necessarily the same thing as a sharp bend.
Use k factor calculator to calculate k factor values.
Die edge radius in.
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.
Alternatively you can design with.
As a result overall sheet length increases.
Use this document to choose values that are both manufacturable and meet your needs.
Whereas the outer surface is stretched.
Enter flange length internal radius and thickness values.
Ultimate tensile strength psi.
Then input the bend angle to get the arc length bend allowance and bend deduction.
Most sheet metal materials will conform to the calculations.
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 calculator bend allowance equations and calculator.
Input material thickness and and inner radius to get the data of k factor y factor neutral layer.
To solve this cmrp provides easy to use measurement calculators.
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.
