Sheet Metal Bend Radius Calculator

Sheet metal calculator bend allowance equations and calculator.

Sheet metal bend radius calculator.

Punch edge radius in. 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. Ultimate tensile strength psi. Cells on the right will output the desired values.

You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k. Bend allowance sheet metal change inlength due to bending operation calculator. Most sheet metal materials will conform to the calculations. The material thickness will be measured in decimal form not by the gauge number.

Then input the bend angle to get the arc length bend allowance and bend deduction. Use this document to choose values that are both manufacturable and meet your needs. Then input leg length a and b to get the flat size of the sheet. Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal.

Material thickness microform bend deduction. Therefore the bend allowance added to the flange lengths is equal to the total flat. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. Most sheet metal materials.

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. Bend allowance calculator tells you the amount of metal to add. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend.

Inside bend radius r inches must be greater than 90 and less than 180 degrees. Die edge radius in. Bend formula example. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.

Automatically calculate bend deduction bend allowance and k factor for sheet metal fabrication and forming. Microform precision llc 4244 south market. Online bend deduction 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.

Bend radii minimum bend sizes. The most important consideration when bending metal on a brake is the minimum bend radius.
