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:
- 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.
- 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.
- Repeat for Part 3, 4, 5, etc.:
- The results will show some variation in equipment because of the variation in destructive tests:
- 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).
You don't have to be an expert.
