0.25 offset of inner surface of poloidal break leaves 0.073” clearance
Based on final C2 measurements, MC C2 poloidal break extends inward 0.19” along the full surface. See slide 24.
15
MTM metrology data points shown as white points.
Steve’s original metrology data points are red points
Interfacing Type-C wings is shown in overlay with underside surface represented.
16
There are minimum points to inspect but Se141-116-wing-c clearance looks okay with a 0.222” clearance identified at one location. The underside surface of the wing is typical out by +0.025”, leaving a minimum clearance of 0.197”.

The surface offset of pints in the pink area is in the range of +.021” to +.039” except where noted.
The surface offset of pints in the blue area is in the range of +.075” to .102”. Nominal surface cut is .12” Are we deep enough?
Offset of pints in the orange area is in the range of .020” to .037”.
The values shown is the machined surface of the large Wing C male side. It will interface with the surface shown in slide 6.

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.
The C5 small wing geometry is similar to C2 (see slide 30).

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.

1. 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.
2. The first MC is positioned on the Stage 2 support stand and secured in place.
3. A reference coordinate system (to be designated ACS0) will be determined through metrology measurement of the first MC, referencing the 8 monuments.
