Figure 1:1. Folded flange, general definitions
|
Base line |
The line to which the flange geometry will be added. For brackets this line usually goes through the top of the bracket toes. |
|
Marking line |
A line on the flange indicating where the bending tool should be placed while bending the flange. |
|
Knuckle point |
Some flange ends have a profile-looking shape. Their geometries have in one point a knuckle (the knuckle point) which corresponds to the top of the 'toe' of the 'end cut'. Its position is defined by the orthogonal distance from the base line. |
|
FLA_W |
The width of the flange, before it has been bent. FLA_W is the orthogonal distance between the base line and the edge of the flange. |
|
W_KN |
The orthogonal distance between the base line and the knuckle point. |
|
MARK_D |
The orthogonal distance between the base line and the marking line. |
|
Bending radius |
The radius on top of the bending tool. |
