Hi Everybody,
I don't know if this question has already been asked, but here he comes...
I have a question concerning p60 of the MSA manual (3th edition): when you do an MSA study on e.g. a new measurement fixture, which TV do you then use?
On p60 there is mentionned that you can do the analysis based on the process variation or based on tolerance. There is mentionned also "Either or both approaches can be taken depending on the intended use of the measurement system and the desire of the customer".
The customer sent us an MSA sheet with a TV based on process variation. If I use this, my %R&R is not good (because the results are very similar to eachother). If I use a sheet with the TV based on the tolerance, my results are off course much better...
Which way of calculating the TV should I use and when do I use the other method?
Thanks in advance for the help...
