Sheet Metal Radius Calculator

Alternatively you can design with.

Sheet metal radius calculator.

This page also includes a link to a on line sheet metal bend allowance calculator. The most important consideration when bending metal on a brake is the minimum bend radius. Use this document to choose values that are both manufacturable and meet your needs. Here again a minimum bend radius is not necessarily the same thing as a sharp bend.

It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Bend allowance calculator tells you the amount of metal to add. You only have to insert interior angle flange lengths k factor inside radius and material thickness. A sharp bend will always be less than a minimum bend radius but a minimum bend radius does not need to be sharp.

The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. 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. As a result overall sheet length increases. Minimum sheet metal flange bend length is required to avoid cracks in the bending area.

Minimum sheet metal flange bend length 3 x sheet thickness bend radius. Most sheet metal materials will conform to the calculations. When it comes to curved steel finding the precise measurements is a challenging undertaking. When sheet metal is bend the inside bending surface is compressed.

Whereas the outer surface is stretched. This change in sheet length depends on the position of neutral axis or k factor. 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. This calculator predicts what the minimum bend radius should be to avoid chacking or orange peeling on the outside radius of the bend.
