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.
Minimum radius on bending 6mm steel sheet.
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.
In steel between 0 5 and 0 8 in.
The problem with bending too tightly.
It is possible to choose other bends if you require but additional lead time and tooling charges may apply.
Bend radii minimum bend sizes.
It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.
Maximum sheet thickness for aluminum and stainless steel is 6 mm.
Maximum weight is 40 kg.
Use this document to choose values that are both manufacturable and meet your needs.
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.
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.
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 tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
Maximum sheet thickness for all other steel is 6 mm.
Picture a sheet of 0 100 in thick material 2 54 mm.
If the product contains one or more sharp bends use the dimensions from the sharp tables for all bends in.
These dimensions are all in relation to a 90 angle.
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.
The bending of sheet metal with a punch and an array mounted at a folder is quite natural and normal.
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.
If a piece of material is bent too tightly problems can occur.
To keep it simple i also use a 2 mm inside radius.
Let s say i have a 2 mm thick sheet and i want to bend it.
The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase.
In principle does not seem that this operation is complicated and difficult.
