Sheet Metal Bend Radius Calculator

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.

Sheet metal bend radius calculator.

Most sheet metal materials will conform to the calculations. As this happens you gain a small amount of total length in your part. To calculate r which is the radius of the arc on the neutral axis we can use the following equation. Discover all our calculation tools in the calculators section of the top menu.

To calculate the neutral axis distance from the inner face t we can subtract inside bend radius from r. Therefore the bend deduction equals the difference between the mold line lengths and the total flat length. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Microform precision llc 4244 south market.

The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. Use this document to choose values that are both manufacturable and meet your needs. Material thickness microform bend deduction.

The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length. You only have to insert interior angle flange lengths k factor inside radius and material thickness. The bend allowance added to the flange lengths is equal to the total flat length of the part. Ultimate tensile strength psi.

Punch edge radius in. Automatically calculate bend deduction bend allowance and k factor for sheet metal fabrication and forming. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. A is the bending angle in the above equation so.

Online bend deduction calculator. Die edge radius in. Cells on the right will output the desired values. This page also includes a link to a on line sheet metal bend allowance calculator.

Sheet metal calculator bend allowance equations and calculator. Bend radii minimum bend sizes. 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.

Precision sheet metal fabrication request a quote. Therefore the bend allowance added to the flange lengths is equal to the total flat. And by having t and the sheet thickness t we can calculate the k factor as follow.
