Bend radii minimum bend sizes.
Minimum radius on bending 6mm steel sheet.
Maximum sheet thickness for all other steel is 6 mm.
Discover all our calculation tools in the calculators section of the top menu.
It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.
The problem with bending too tightly.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
These dimensions are all in relation to a 90 angle.
If a piece of material is bent too tightly problems can occur.
I can now see that the minimum flange length is 8 5 mm for such a bend so i have to keep it in mind when designing.
The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase.
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.
Maximum weight is 40 kg.
If the product contains one or more sharp bends use the dimensions from the sharp tables for all bends in.
In principle does not seem that this operation is complicated and difficult.
Maximum sheet thickness for aluminum and stainless steel is 6 mm.
By multiplying the material thickness by 0 63 63 percent the natural minimum radius can be determined in this case 0 063 in.
The bending of sheet metal with a punch and an array mounted at a folder is quite natural and normal.
The minimum inside bend radius is even larger when bending with the grain.
In steel between 0 5 and 0 8 in.
Thick grade 350 and 400 may have a minimum bend radius of 2 5 times the material thickness when transverse bending while longitudinal bending may require a minimum bend radius that s 3 75 times the material thickness see figure 1.
Picture a sheet of 0 100 in thick material 2 54 mm.
Use this document to choose values that are both manufacturable and meet your needs.
Let s say i have a 2 mm thick sheet and i want to bend it.
Maximum dimensions are 2980 x 1200 mm.
We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.
Since commercial sheet metal bending can be done with less concern for stresses caused during forming operation the radius can be near zero for thin sheet metal.
Each and every bend in a piece of sheet metal has a certain minimum internal radius that needs to be taken into account when planning the design of a sheet metal form.
These formulas are valid but they do not take into account whether the bend to be produced is a sharp or radius bend.
The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.
