Calculate Bend Angle Sheet Metal

The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance.

Calculate bend angle sheet metal.

The material thickness will be measured in decimal form not by the gauge number. Bend angle a degrees thickness t inches inside bend radius r inches must be greater than 90 and less than 180 degrees. You only have to insert interior angle flange lengths k factor inside radius and material thickness. 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. Online bend deduction calculator. A is the bending angle in the above equation so. Bending angles greater than 90 degrees.

As this happens you gain a small amount of total length in your part. To calculate the neutral axis distance from the inner face t we can subtract inside bend radius from r. Material thickness microform bend deduction. Like previous scenarios let s start by calculating leg length 1.

The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend. A bend equal to 90. Most sheet metal materials will conform to the calculations. Tonnage charts bend deduction bend allowance and other forming calculations and charts often refer to a 90 bend.

Cells on the right will output the desired values. This type of angle can also be referred to as a square bend. Precision sheet metal fabrication request a quote. You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k.

Effective k factor. Right angles are the most common feature found in most sheet metal fabrication. And by having t and the sheet thickness t we can calculate the k factor as follow. Automatically calculate bend deduction bend allowance and k factor for sheet metal fabrication and forming.

The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length. Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal.
