Sheet Metal Bend Radius Calculator

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 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. Therefore the bend deduction equals the difference between the mold line lengths and the total flat length. Most sheet metal materials will conform to the calculations. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend.

Automatically calculate bend deduction bend allowance and k factor for sheet metal fabrication and forming. The bend deduction sometimes called the bend compensation describes how much the outside of the sheet has been stretched. Discover all our calculation tools in the calculators section of the top menu. Precision sheet metal fabrication request a quote.

The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length. Ultimate tensile strength psi. Punch edge radius in. Die edge radius in.

The bend allowance added to the flange lengths is equal to the total flat length of the part. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. Online bend deduction calculator. You only have to insert interior angle flange lengths k factor inside radius and material thickness.

Therefore the bend allowance added to the flange lengths is equal to the total flat. Cells on the right will output the desired values. The most important consideration when bending metal on a brake is the minimum bend radius. 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.

Most sheet metal materials. 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. Inside bend radius r inches must be greater than 90 and less than 180 degrees.

The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. Microform precision llc 4244 south market. Material thickness microform bend deduction. Bend formula example.

Bend allowance calculator tells you the amount of metal to add. Bend allowance sheet metal change inlength due to bending operation calculator.
