# Calculated Feature: Gage R&R?

## Calculated Feature: Gage R&R?

(OP)
-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"?
