I have just received 2 PPAP submissions from a new supplier for two different size steel tubes. Going through the GR&Rs I noticed that the Inside Diameter GR&R for both size tubes are identical, number for number. I have looked for the gauge that they have listed on the report (Mitutoyo 3 pt bore gauge Model# 92865) but after contacting Mitutoyo
there is no 92865 (they said that number might be a serial number off of the indicator).
The ID of the 2 tubes are 42mm and 53mm (approx). Mitutoyo
told me that they do not have a bore gauge which covers both dimensions at the same time without changing gauging heads. This looks like a cookie cutter GR&R to me. So the question is; would you accept these GR&Rs knowing that they probably were not done on the material listed but done on a similar material with an unknown diameter.
To boot the % R&R was 17.1%
