Gage R&R Studies for Process Monitoring Instruments?

Sir,
Is R & R study required for process monitoring instruments or is it only for the product monitoring/measuring instruments only.

I'll try to give you my layman's answer. I am not an MSA / R & R expert, rather I am a metrology engineer with 25 years experience (so take my attempt from that perspective).

R& R is needed for any measuring instrument whose readings/accuracy/stability you depend upon for product specs. I don't know what aspect of the production you are monitoring, but my guess is (based on your wording) that it may be needed. If you are monitoring a quantitative specified parameter or using readings from this monitor to determine whether you are in or out of control on your process, I would think, yes.

If you could elaborate a little more, that may be helpful. I understand if you don't want to put actual process details on the web (you could put fictitious representations of the process).

Jerry is, as always, correct. However the key word in your question:

-> Is R & R study required for process monitoring
-> instruments or is it only for the product
-> monitoring/measuring instruments only

Is the word required. Do you mean required by QS-9000 or ISO 9001:2000?

In the world of Best Practices you would do an R&R on both inspection/test and process instruments, as Jerry points out. But, as Jerry also says, we need more info to go beyond these general statements.

A gage is a gage is a gage,

If it monitors a process or product it needs to be evaluated. Just a good business practice.

A Method for Evaluation

Can you recommend a method? You really can't do an R&R per se on a process gage.

See Gage R&R with Automated Gages - No Operator Bias for some thoughts. Not directly related, but some interesting thoughts.
