Sheet Metal Radius Calculator

It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.

Sheet metal radius calculator.

Here again a minimum bend radius is not necessarily the same thing as a sharp bend. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. This change in sheet length depends on the position of neutral axis or k factor. Sheet metal calculator bend allowance equations and calculator.

Minimum sheet metal flange bend length 3 x sheet thickness bend radius. Punch edge radius in. This tool allows you to determine tonnage internal radius v die opening and minimum flange you just have to insert the characteristics of the sheet metal to be bent. 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.

Best way to calculate k factor in sheet metal is by reverse engineering. To solve this cmrp provides easy to use measurement calculators. This page also includes a link to a on line sheet metal bend allowance calculator. When it comes to curved steel finding the precise measurements is a challenging undertaking.

Minimum sheet metal flange bend length is required to avoid cracks in the bending area. When sheet metal is bend the inside bending surface is compressed. A sharp bend will always be less than a minimum bend radius but a minimum bend radius does not need to be sharp. It shall be equal to three times of sheet thickness plus bend radius.

The most important consideration when bending metal on a brake is the minimum bend radius. You only have to insert interior angle flange lengths k factor inside radius and material thickness. Use this document to choose values that are both manufacturable and meet your needs. Discover all our calculation tools in the calculators section of the top menu.

Most sheet metal materials will conform to the calculations. Bend allowance calculator tells you the amount of metal to add. Cells on the right will output the desired values. 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. Die edge radius in. Whereas the outer surface is stretched.
