Hi friends,
can some body help me !
During Audits I'm facing lot of queries with the external auditors(ISO/TS16949)
,What is the corrective action u h've taken while the GRR is exceeding >30%.
For this i found one alternative, i.e In MSA 3rd edition Chap-V -sec-d under reducing variation through multiple readings.
They given one Ex :% of Tol GRR variation is 25.5%, With a 6 Sigma spread equal to 0.24 ,If we reduce this fig. to atleast 15%,Which would have an equivalent 6 sigma spread of 0.14.
Pl. can anybody explain how the figure(0.24&0.14) arrived .
Thanks,
