Sheet Metal Radius Calculator

Punch edge radius in.

Sheet metal radius calculator.

Sheet metal bending parameters calculator this tool allows you to determine tonnage internal radius v die opening and minimum flange. To solve this cmrp provides easy to use measurement calculators. Die edge radius in. When sheet metal is bend the inside bending surface is compressed.

Cells on the right will output the desired values. Whereas the outer surface is stretched. Keep default values in calculator as zero. 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.

Then input leg length a and b to get the flat size of the sheet. Ultimate tensile strength psi. Enter k factor values. When it comes to curved steel finding the precise measurements is a challenging undertaking.

This page also includes a link to a on line sheet metal bend allowance calculator. Use k factor calculator to calculate k factor values. A sharp bend will always be less than a minimum bend radius but a minimum bend radius does not need to be sharp. Value of bend deduction and flat pattern are shown in result section.

Then input the bend angle to get the arc length bend allowance and bend deduction. You only have to insert interior angle flange lengths k factor inside radius and material thickness. You just have to insert the characteristics of the sheet metal to be bent. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal.

Alternatively you can design with. Here again a minimum bend radius is not necessarily the same thing as a sharp bend. Sheet metal calculator bend allowance equations and calculator. As a result overall sheet length increases.

Use this document to choose values that are both manufacturable and meet your needs. Input material thickness and and inner radius to get the data of k factor y factor neutral layer. Here are the steps to be followed to calculate sheet metal flat length. This change in sheet length depends on the position of neutral axis or k factor.

Best way to calculate k factor in sheet metal is by reverse engineering. Most sheet metal materials will conform to the calculations.
