Sheet Metal Radius Calculator

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.

Sheet metal radius calculator. Punch edge radius in. The most important consideration when bending metal on a brake is the minimum bend radius. Minimum sheet metal flange bend length is required to avoid cracks in the bending area. As a result overall sheet length increases.

You only have to insert interior angle flange lengths k factor inside radius and material thickness. This calculator predicts what the minimum bend radius should be to avoid chacking or orange peeling on the outside radius of the bend. Cells on the right will output the desired values. A sharp bend will always be less than a minimum bend radius but a minimum bend radius does not need to be sharp.

Most sheet metal materials will conform to the calculations. To solve this cmrp provides easy to use measurement calculators. Bend allowance calculator tells you the amount of metal to add. Die edge radius in.

Minimum sheet metal flange bend length 3 x sheet thickness bend radius. Whereas the outer surface is stretched. Here again a minimum bend radius is not necessarily the same thing as a sharp bend. This change in sheet length depends on the position of neutral axis or k factor.

Sheet metal calculator bend allowance equations and calculator. It shall be equal to three times of sheet thickness plus bend radius. Alternatively you can design with. When sheet metal is bend the inside bending surface is compressed.

Best way to calculate k factor in sheet metal is by reverse engineering. This page also includes a link to a on line sheet metal bend allowance calculator. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.

Ultimate tensile strength psi. When it comes to curved steel finding the precise measurements is a challenging undertaking. Discover all our calculation tools in the calculators section of the top menu.
