AIRBUS Machined Part Modelling for CATIA V5 AP2257 4 Detailed modelling process per type of difficulty 4.1 4 or 5 axis pocket with closed angle 4.1.1 Producing 2.5 axis pocket " Creation of pocket limit defined by a surface (S) - Definition of the pocket profile. Make the following steps in a new open body • In the WireFrame Surface Design workbench, make the intersection , the curve (C), between the top of part & an offset surface (Ss) of the small integral stiffener thickness (see figure ‘Intersection solid & Ss). The aim is to obtain the trace of the top part let by the cutting tool. The machining is made on 2.5 axis mode along Z. Ss Intersection solid & (Ss) C • In a second step, project (C) on the reference plane (Z= 0 mm). We obtain (C1) (see figure ‘curve projection’). • The profile is defined; we can create an C extruded surface (S1) defined by the (C1) curve and the Z-axis. • Define an offset surface (S1off) from (S1). The distance between the 2 surfaces is equal to 0.5 mm. This overthickness allow to let material to remove for the 5 axis machining (see paragraph 4.1.2) #(S1off) will be used to limit the pocket.

AIRBUS Machined Part Modelling for CATIA V5 AP2257 • In the Part Design workbench, insert a new body • Create the following in sketch in the Z=0 mm plan Pocket 1 & 2 section ! The pocket 1 section is the same as the pocket 3 one. By consequence, we are going to use this sketch for the pocket 1 & the pocket 3 definition. In that way, a modification in this sketch will impact the 2 pockets Issue:Draft A1 Date: 13 February 2002 Page 21 of 46
