Sheet Metal Bend Radius Calculator

Punch edge radius in.

Sheet metal bend radius calculator.

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. 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. Discover all our calculation tools in the calculators section of the top menu. Ultimate tensile strength psi.

And by having t and the sheet thickness t we can calculate the k factor as follow. Bend radii minimum bend sizes. Precision sheet metal fabrication request a quote. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal.

You only have to insert interior angle flange lengths k factor inside radius and material thickness. To calculate r which is the radius of the arc on the neutral axis we can use the following equation. Microform precision llc 4244 south market. Material thickness microform bend deduction.

To calculate the neutral axis distance from the inner face t we can subtract inside bend radius from r. Therefore the bend allowance added to the flange lengths is equal to the total flat. Automatically calculate bend deduction bend allowance and k factor for sheet metal fabrication and forming. Online bend deduction calculator.

The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. As this happens you gain a small amount of total length in your part. A is the bending angle in the above equation so. Bend formula example.

The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend. Sheet metal calculator bend allowance equations and calculator. Most sheet metal materials will conform to the calculations. Use this document to choose values that are both manufacturable and meet your needs.

Cells on the right will output the desired values. The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length. Therefore the bend deduction equals the difference between the mold line lengths and the total flat length. Die edge radius in.

The bend deduction sometimes called the bend compensation describes how much the outside of the sheet has been stretched. 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. This page also includes a link to a on line sheet metal bend allowance calculator.
