Sheet Metal Bend Radius Calculator
Most sheet metal materials will conform to the calculations.
Sheet metal bend radius calculator. Microform precision llc 4244 south market. Online bend deduction calculator. Ultimate tensile strength psi. You only have to insert interior angle flange lengths k factor inside radius and material thickness.
Then input the bend angle to get the arc length bend allowance and bend deduction. The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance. Bend radii minimum bend sizes. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend.
Input material thickness and and inner radius to get the data of k factor y factor neutral layer. Sheet metal calculator bend allowance equations and 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 allowance sheet metal change inlength due to bending operation calculator.
You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k. Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal. Then input leg length a and b to get the flat size of the sheet. Bend formula example.
Therefore the bend allowance added to the flange lengths is equal to the total flat. 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. Use this document to choose values that are both manufacturable and meet your needs.
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. This page also includes a link to a on line sheet metal bend allowance calculator. The material thickness will be measured in decimal form not by the gauge number.
It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Precision sheet metal fabrication request a quote. Most sheet metal materials. Automatically calculate bend deduction bend allowance and k factor for sheet metal fabrication and forming.
Bend allowance calculator tells you the amount of metal to add. Punch edge radius in.
