How to do Gage R&R When Parts are Destroyed When Measured

QI Macros has a ready made template for you.

Use QI Macros Gage R&R Study Template to Perform Non-replicable Destructive Testing:

Select your parts as follows:

1. The samples for Part 1 (that will be repeated by a single operator, and those to be reproduced by another operator) should come from as nearly a homogeneous sample/batch as possible.
2. The samples used as Part 2 should be from a different batch, different production run, or have sufficient time to allow long term variation to occur.
3. Repeat for Part 3, 4, 5, etc.:
   



4. The results will show some variation in equipment because of the variation in destructive tests:



5. The Gage R&R template will show that 21.1% for the %R&R means that the gage system may be acceptable (given destructive testing has occurred and we can't use the same part twice).
