Sheet Metal Bend Radius Calculator

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.

Sheet metal bend radius calculator.

The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal. Sheet metal calculator bend allowance equations and calculator. Therefore the bend allowance added to the flange lengths is equal to the total flat.

Most sheet metal materials will conform to the calculations. Ultimate tensile strength psi. Bend allowance calculator tells you the amount of metal to add. Material thickness microform bend deduction.

The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. Therefore the bend deduction equals the difference between the mold line lengths and the total flat length.

Bend allowance sheet metal change inlength due to bending operation calculator. 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. The most important consideration when bending metal on a brake is the minimum bend radius.

Inside bend radius r inches must be greater than 90 and less than 180 degrees. The bend allowance added to the flange lengths is equal to the total flat length of the part. Precision sheet metal fabrication request a quote. The bend deduction sometimes called the bend compensation describes how much the outside of the sheet has been stretched.

Punch edge radius in. As this happens you gain a small amount of total length in your part. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. Most sheet metal materials.

Bend formula example. You only have to insert interior angle flange lengths k factor inside radius and material thickness. Discover all our calculation tools in the calculators section of the top menu. Microform precision llc 4244 south market.

Cells on the right will output the desired values. 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.
