Does anyone out there do sorting with Vision systems or E-current? If so, do you do MSA on the equipment using variable or attribute data? What do you find is valid for qualifications?
I currently bring the equipment in using the numerical values recorded for test pieces (traceable to NIST) run 3 times but with only 1 operator as the equipment feed is automatic. Once the equipment is in the system, it becomes a go/no-go gage rejecting or approving parts based on a window specified in the programming. Rabbits (test pieces) are run at various increments to verify the accuracy of the process.
Questions - Would you consider this adequate? Would you submit the original numerical MSA when doing PPAP or would you send an attribute study using the good/bad rabbits (which, by the way, aren't always available at the start of a project)? If you would do something else, what would that be?
Thanks in advance.
