Calculate Bend Angle Sheet Metal

Online bend deduction calculator.

Calculate bend angle sheet metal. You only have to insert interior angle flange lengths k factor inside radius and material thickness. This type of angle can also be referred to as a square bend. Therefore the bend allowance added to the flange lengths is equal to the total flat length. Right angles are the most common feature found in most sheet metal fabrication.

A is the bending angle in the above equation so. The material thickness will be measured in decimal form not by the gauge number. Most sheet metal materials will conform to the calculations. To calculate the neutral axis distance from the inner face t we can subtract inside bend radius from r.

The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length. Bending angles greater than 90 degrees. Automatically calculate bend deduction bend allowance and k factor for sheet metal fabrication and forming. Microform precision llc 4244 south market court suite.

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. And by having t and the sheet thickness t we can calculate the k factor as follow. Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal.

A bend equal to 90. 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. You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k.

Material thickness microform bend deduction. As this happens you gain a small amount of total length in your part. Precision sheet metal fabrication request a quote. Like previous scenarios let s start by calculating leg length 1.

The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance. Cells on the right will output the desired values.
