Sheet metal bend line calculator.

In the example above it is indicated by a dashed blue line. Bend to mold sheet metal line distance calculator determines the bend line to mold allowance when forming sheet metal. As this happens you gain a small amount of total length in your part. Most sheet metal materials will conform to the calculations.

You only have to insert interior angle flange lengths k factor inside radius and material thickness. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. The bend deduction sometimes called the bend compensation describes how much the outside of the sheet has been stretched. Code to add this calci to your website.

In the example above it is indicated by a dashed blue line. Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal. The values of the setback bend allowance and bend deduction can be calculated from the sheet thickness bend radius bend angle and k factor. Most sheet metal materials will conform to the calculations.

Therefore the bend deduction equals the difference between the mold line lengths and the total flat length. The bend allowance is the amount of the neutral axis that bends. Most sheet metal materials will conform to the calculations. Learn more about bending.

The bend allowance added to the flange lengths is equal to the total flat length of the part. 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. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched.

Most sheet metal materials will conform to the calculations. As this happens you gain a small amount of total length in your part. Although it is an option for calculating a bend in some cad programs such as solid works it is not often referred to in the actual manufacturing process since. This page also includes a link to a on line sheet metal bend allowance calculator.

The mold line lengths are the distances measured to the outside mold line and are equal to the flange lengths plus the setback. 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. The following illustration shows the equation calculation for determining the bend line to mold allowance when forming sheet metal.
