Sheet metal bend radius calculator.

Precision sheet metal fabrication request a quote. Bend allowance sheet metal change inlength due to bending operation calculator. Punch edge radius in. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.

Use this document to choose values that are both manufacturable and meet your needs. The material thickness will be measured in decimal form not by the gauge number. This page also includes a link to a on line sheet metal bend allowance calculator. Microform precision llc 4244 south market.

Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal. Bend allowance calculator tells you the amount of metal to add. Most sheet metal materials. Automatically calculate bend deduction bend allowance and k factor for sheet metal fabrication and forming.

Then input leg length a and b to get the flat size of the sheet. The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance. The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length. 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. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. You only have to insert interior angle flange lengths k factor inside radius and material thickness. Bend formula example.

Cells on the right will output the desired values. Material thickness microform bend deduction. Ultimate tensile strength psi. The most important consideration when bending metal on a brake is the minimum bend radius.

Online bend deduction calculator. Inside bend radius r inches must be greater than 90 and less than 180 degrees. Most sheet metal materials will conform to the calculations. Then input the bend angle to get the arc length bend allowance and bend deduction.

Sheet metal calculator bend allowance equations and calculator. Therefore the bend allowance added to the flange lengths is equal to the total flat.
