To keep it simple i also use a 2 mm inside radius.
Minimum radius on bending 6mm steel sheet.
Maximum sheet thickness for aluminum and stainless steel is 6 mm.
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.
Maximum weight is 40 kg.
Discover all our calculation tools in the calculators section of the top menu.
By multiplying the material thickness by 0 63 63 percent the natural minimum radius can be determined in this case 0 063 in.
Picture a sheet of 0 100 in thick material 2 54 mm.
In principle does not seem that this operation is complicated and difficult.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.
Bend radii minimum bend sizes.
The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.
These dimensions are all in relation to a 90 angle.
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 dimensions are 2980 x 1200 mm.
Use this document to choose values that are both manufacturable and meet your needs.
These formulas are valid but they do not take into account whether the bend to be produced is a sharp or radius bend.
It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.
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 minimum inside bend radius is even larger when bending with the grain.
It is possible to choose other bends if you require but additional lead time and tooling charges may apply.
Maximum sheet thickness for all other steel is 6 mm.
Let s say i have a 2 mm thick sheet and i want to bend it.
The problem with bending too tightly.
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.
The bending of sheet metal with a punch and an array mounted at a folder is quite natural and normal.
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.
In steel between 0 5 and 0 8 in.
If the product contains one or more sharp bends use the dimensions from the sharp tables for all bends in.
