Calculate Bend Angle Sheet Metal

Automatically calculate bend deduction bend allowance and k factor for sheet metal fabrication and forming.

Calculate bend angle sheet metal.

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. Like previous scenarios let s start by calculating leg length 1. And by having t and the sheet thickness t we can calculate the k factor as follow. A is the bending angle in the above equation so.

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. Material thickness microform bend deduction. Right angles are the most common feature found in most sheet metal fabrication.

Cells on the right will output the desired values. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. Tonnage charts bend deduction bend allowance and other forming calculations and charts often refer to a 90 bend. Therefore the bend allowance added to the flange lengths is equal to the total flat length.

The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance. 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. Bend angle a degrees thickness t inches inside bend radius r inches must be greater than 90 and less than 180 degrees.

A bend equal to 90. Precision sheet metal fabrication request a quote. As this happens you gain a small amount of total length in your part. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend.

This type of angle can also be referred to as a square bend. Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal. Bending angles greater than 90 degrees. Microform precision llc 4244 south market court suite.

The material thickness will be measured in decimal form not by the gauge number. You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k.
