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.
