Sheet Metal Bend Line Calculator

The following illustration shows the equation calculation for determining the bend line to mold allowance when forming sheet metal.

Sheet metal bend line calculator.

As this happens you gain a small amount of total length in your part. Learn more about bending. Most sheet metal materials will conform to the calculations. Most sheet metal materials will conform to the calculations.

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. Therefore the bend deduction equals the difference between the mold line lengths and the total flat length. 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. As this happens you gain a small amount of total length in your part.

When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. In the example above it is indicated by a dashed blue line. You only have to insert interior angle flange lengths k factor inside radius and material thickness. Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal.

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 bend deduction sometimes called the bend compensation describes how much the outside of the sheet has been stretched. This page also includes a link to a on line sheet metal bend allowance calculator.

The bend allowance added to the flange lengths is equal to the total flat length of the part. Most sheet metal materials will conform to the calculations. Code to add this calci to your website. This page also includes a link to a on line calculator.

Most sheet metal materials will conform to the calculations. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. Cells on the right will output the desired values. Bend to mold sheet metal line distance calculator determines the bend line to mold allowance when forming sheet metal.

When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. 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.
