Sheet Metal Bend Radius Calculator

Punch edge radius in.

Sheet metal bend radius calculator.

Online bend deduction calculator. Microform precision llc 4244 south market. Bend allowance sheet metal change inlength due to bending operation calculator. Bend formula example.

Die edge radius in. Automatically calculate bend deduction bend allowance and k factor for sheet metal fabrication and forming. The most important consideration when bending metal on a brake is the minimum bend radius. Input material thickness and and inner radius to get the data of k factor y factor neutral layer.

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. Most sheet metal materials. Sheet metal calculator bend allowance equations and calculator.

Then input leg length a and b to get the flat size of the sheet. Most sheet metal materials will conform to the calculations. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend.

The material thickness will be measured in decimal form not by the gauge number. Precision sheet metal fabrication request a quote. Therefore the bend allowance added to the flange lengths is equal to the total flat. Use this document to choose values that are both manufacturable and meet your needs.

Then input the bend angle to get the arc length bend allowance and bend deduction. Material thickness microform bend deduction. Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal. 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. You only have to insert interior angle flange lengths k factor inside radius and material thickness. The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance. 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.

You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k. Inside bend radius r inches must be greater than 90 and less than 180 degrees.
