Gage R&R required on 6" rules, tape rules, verniers or micrometers?

R and R

We, as a company have started to get involved with the automotive industry for our product. My understanding is that they as a customer require gage R and R studies. However, I am a little unclear as to what constitutes a gage? Would I have to carry out studies on such things as 6" rules, tape rules, verniers or micrometers?

David,

Mic's and verniers and the like, if you are using them to assess product quality they need to be done.

Steel rules etc.... depends what you are using them for.


If you need any help, please feel free to give me a call / email and arrange a visit - I'm based in Birmingham.

Note that the QS9000 manual on MSA studies, an excellent reference source, says common sense should prevail when conducting MSA studies, and may not be necessary on standard gauging.

David,

First and foremost, as Martin suggested, you should get a copy of AIAG third edition MSA manual (if you haven't got it already) which explains R&R studies in a great detail. www.aiag.org

Generally, Tape measures may not require extensive MSA studies. Refer the following thread:
https://www.elsmar.com/Forums/showthread.php?s=&threadid=5719

MSA studies. R&R, Bias, Linearity & Stability, should be conducted on verniers and micrometers included in the control plan: subject to criticality of the characteristic being measured, customer's requirements etc etc...

Just do a forum search on R&R and you are sure to find wealth of info.
