Softening of Sharp Corners of Folded Flanges

All types of folded flanges specified above have at least one knuckle in the flange end contour and flange end types 3 - 9 have a second knuckle at the start of the "snipe" (sloped part of flange end contour).

However, there is an option to soften these knuckles by a fillet arc. The radius of this arc is defined in the FLA_END statement (see paragraph The FLA_END Statement below).

For flange ends with more than one knuckle the same radius will be used for both fillet arcs.
