-I need to measure a gap feature of an assembly. The gap specification is 0.010" +/- 0.002". The gap feature cannot be directly measured without cross-sectioning (destructive).
-One potential way to calculate the gap is to measure length of two components of the assembly. The difference between the two lengths is the assembly gap.
-To demonstrate gage capability, I did gage r&r studies on the two lengths. The %GRR is 3% and 8% respectively.
My question: How can I use the %GRR for the lengths and make an assessment if the calculated assembly gap (0.010" +/- 0.002") are good? Can I spool the sigma R&R for the lengths and compares to +/- 0.002"?
