We deal with Plastic Injection Moulded components and measure direct to CAD data using a CMM. However the CMM measurements are not used in a production environment but more so for ISIR and Annual recertification. Our Control Plans relate to MSA on in process checks but not to the ISIR process.
Considering we have approximately 50 measurement points on components, we do not wish to perform an MSA on each measurement point. At present we get around this by picking a point in X, Y and Z axis on the part and performing the study on these three points.
I think this covers the MSA requirements for R&R in that we are proving the gauge, person and part. However I am not sure whether this is the correct way to go. My gut feeling is that we should perform the study on each measurement point but this would be a lengthy exercise and I don't want to waste my operators time.
Does this seem OK to everyone, or does anyone have similar experiences they have learnt from.
