Sheet Metal Bending Radius Calculation

Material to the inside of this line ought to compress whereas the material on the outside of it should expand.

Sheet metal bending radius calculation.

Ultimate tensile strength psi. Sheet metal calculator bend allowance equations and calculator. Use this document to choose values that are both manufacturable and meet your needs. A is the bending angle in the above equation so.

Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. The white dashed line on the part shown above represents the neutral axis which is the theoretical point in the material that does not change during the course of forming. 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. This page also includes a link to a on line sheet metal bend allowance calculator.

This is done through the application of force on a workpiece. The force must exceed the material s yield strength to achieve a plastic deformation. Learn more about bending. You only have to insert interior angle flange lengths k factor inside radius and material thickness.

Cells on the right will output the desired values. The values of the setback bend allowance and bend deduction can be calculated from the sheet thickness bend radius bend angle and k factor. The mold line lengths are the distances measured to the outside mold line and are equal to the flange lengths plus the setback. Discover all our calculation tools in the calculators section of the top menu.

Bending is one of the most common sheet metal fabrication operations. The following illustration shows the equation calculation for determining the bend allowance when forming 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. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched.

To calculate the neutral axis distance from the inner face t we can subtract inside bend radius from r. To calculate r which is the radius of the arc on the neutral axis we can use the following equation. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.

This tool allows you to determine tonnage internal radius v die opening and minimum flange you just have to insert the characteristics of the sheet metal to be bent. Bend radii minimum bend sizes. As this happens you gain a small amount of total length in your part. Die edge radius in.
