Flange Extension in Tapered Endcuts

By applying a special rule, the knuckle angle and flange extension of tapered endcuts for L-bars and T-bars may be automatically defined at modelling time. The flange geometry of such endcuts is illustrated below. When tapered endcuts are modelled a 'b'-measure is defined, as indicated in the figure. This rule defines, per endcut type, the knuckle angle and flange extension as a function of the difference of the profile height and the b-measure (that is normally the height of another profile which the current profile abuts).

The customer can control the knuckle angle and flange extension via a special file in TIL-format.

The file consists of a number of statements, each consisting of the CUT keyword, an endcut type and a number of triples of /HKN-attributes, /ANG-attributes and /EXT-attributes.

Example of a text file defining knuckle angle and flange extension of tapered endcuts:
