Calculate Bend Angle 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.

Calculate bend angle sheet metal.

A is the bending angle in the above equation so. As this happens you gain a small amount of total length in your part. Bend angle a degrees thickness t inches inside bend radius r inches must be greater than 90 and less than 180 degrees. 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. Most sheet metal materials will conform to the calculations. Therefore the bend allowance added to the flange lengths is equal to the total flat length. The material thickness will be measured in decimal form not by the gauge number.

You only have to insert interior angle flange lengths k factor inside radius and material thickness. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend. Effective k factor. This type of angle can also be referred to as a square bend.

Microform precision llc 4244 south market court suite. To calculate the neutral axis distance from the inner face t we can subtract inside bend radius from r. Right angles are the most common feature found in most sheet metal fabrication. Like previous scenarios let s start by calculating leg length 1.

Tonnage charts bend deduction bend allowance and other forming calculations and charts often refer to a 90 bend. 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. Precision sheet metal fabrication request a quote. Automatically calculate bend deduction bend allowance and k factor for sheet metal fabrication and forming.

And by having t and the sheet thickness t we can calculate the k factor as follow. You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k. Cells on the right will output the desired values. Bending angles greater than 90 degrees.

Material thickness microform bend deduction. Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal.
