0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance.
Bending sheet steel with a small radius.
If you re bending 0 020 thick material use a 0 020 radius.
The bend step is the number of bends which will be used to form the radius.
The hardness of the metal.
Generally speaking the thicker a piece of sheet metal is the wider the internal bend radius will have to be.
It should be noted that the bend angle is also halved from 30 to 15.
To ascertain your k factor inside radius and material thickness expressed as a decimal you should use an bend allowance chart.
As you can see below the difference between 3 and 6 bends is rather significant.

Minimum bend bend radius.
As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be.
The thickness of the metal.
In other words if you re bending 1 8 sheet use a tool with a 1 8 radius to form the inside of the bend.
22 gauge 0 031 0 787mm 0 265 6 73mm.
There are a two major factors that affect how tight you can make the internal radius of a bend in a piece of sheet metal.
You can use this to put a perfectly clean 90 degree inside bend in steel bar or sheet of any width use a cutting disc to slot down through the plate at the.
