Sheet Metal Bend Radius Calculator

Microform precision llc 4244 south market.

Sheet metal bend radius calculator.

To calculate r which is the radius of the arc on the neutral axis we can use the following equation. Use this document to choose values that are both manufacturable and meet your needs. As this happens you gain a small amount of total length in your part. And by having t and the sheet thickness t we can calculate the k factor as follow.

You only have to insert interior angle flange lengths k factor inside radius and material thickness. Therefore the bend deduction equals the difference between the mold line lengths and the total flat length. Understanding the bend allowance and consequently the bend deduction of a part is a crucial first step to understanding how sheet metal parts are fabricated. Ultimate tensile strength psi.

Bend formula example. Sheet metal calculator bend allowance equations and calculator. Precision sheet metal fabrication request a quote. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal.

The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length. The bend allowance added to the flange lengths is equal to the total flat length of the part. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend. Bend radii minimum bend sizes.

It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Automatically calculate bend deduction bend allowance and k factor for sheet metal fabrication and forming. This page also includes a link to a on line sheet metal bend allowance calculator. Punch edge radius in.

Discover all our calculation tools in the calculators section of the top menu. Online bend deduction calculator. 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. Die edge radius in.

A is the bending angle in the above equation so. Therefore the bend allowance added to the flange lengths is equal to the total flat. Material thickness microform bend deduction. To calculate the neutral axis distance from the inner face t we can subtract inside bend radius from r.

When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. Cells on the right will output the desired values.
