  1. Evaluation of metrology data of EOI Type “C” cast part. EOI data: non_stocked_non_srunk_overlay.igs Poe/E file: stb-eoi_overlay-1.prt Date: 8/7/2004 Summary: The metrology data has not been taken in detail in all areas of the part and further data point may be needed. However, with the data supplied it appears that there is sufficient stocked material to allow a machined part to be successfully fabricated. Also a large number of areas has an excess of stocked material which will result in longer machining time. T. Brown

  2. +0.85 There is approximately 1” of stocked material around the “T” section. +1.16 +0.78 +1.05

  5. Metrology points were not found on the outside surface of this wing region. Additional points are needed.

  6. All points are more than .5”off the surface Upper “C” side wing region has positive stock material

  7. -.12 -.03 0.0 -.126 Lower “B” side wing region has small amount of negative stock material but there is excess material on its opposite side.

  8. -.16 -.23 -.27 Small “C” side wing region has negative stock material on the few data points provided. Data point are needed on the outside surface.

  9. +.25 -.01 -.05 -.27 +.138 Part rotated +.097 Some negative stock material on this surface but there is excess material on its opposite side.
