The C5 small wing geometry is similar to C2 (see slide 30). Based on final measurements of C2 and C5 a gap of +0.033 exists at the poloidal break interface area. Local grinding on this wing is needed to increase the gap.

Measured CAD distance with C2 and C5 located in their translated positions. The movement of C2 and C5 was made using Art’s large motion case (r1) provided in email (FW C1-4 Realignment Coordinate Transformations in ProE nomenclature) dated 10/6/06. C2 was positioned using C2r1 data and C5 positioned using C4r1 data. The translated position is based on the CS0 coordinate system.

● ● ● • 8 monuments are located on each mating MC, so positioned that they can be seen by the Lica metrology system which has been optimally positioned. The monuments are to be located on stable surfaces where part deflection is minimal. • The first MC is positioned on the Stage 2 support stand and secured in place. • A reference coordinate system (to be designated ACS0) will be determined through metrology measurement of the first MC, referencing the 8 monuments.
