Sheet Metal Bend Radius Calculator

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

Sheet metal bend radius calculator.

The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. 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. Online bend deduction calculator. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched.

Bend allowance sheet metal change inlength due to bending operation calculator. The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length. Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal. Ultimate tensile strength psi.

You only have to insert interior angle flange lengths k factor inside radius and material thickness. The bend allowance added to the flange lengths is equal to the total flat length of the part. Material thickness microform bend deduction. Discover all our calculation tools in the calculators section of the top menu.

The most important consideration when bending metal on a brake is the minimum bend radius. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. 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.

The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend. 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. As this happens you gain a small amount of total length in your part. This page also includes a link to a on line sheet metal bend allowance calculator.

Die edge radius in. 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. Microform precision llc 4244 south market. Punch edge radius in.

Cells on the right will output the desired values. Most sheet metal materials will conform to the calculations. Bend formula example. Inside bend radius r inches must be greater than 90 and less than 180 degrees.

Sheet metal calculator bend allowance equations and calculator. Bend allowance calculator tells you the amount of metal to add.
