Hello.
We are currently undergoing a launch programme for Flywheels for Ford Motor company.
We have taken receipt of some gauges, one in particular is causing us some headache.
It is an electronic gauge measuring various heights and lengths.
We have issues with a number of measurements. We measure a height on the flywheel from the dayum bore and face using one transducer. During study this transducer has shown to have 9.8%GRR. Our issue is that three other measurements are measured off this transducer/face. This means then that the other measurements start with a 9.8% possible variation. The actual GRR for these dimensions are 18.67%.
I have two questions.....
Do you think this is an exceptable figure to sign off the gauge bearing in mind they are non-critical features?
Will this possible variation increase or decrease our machine capability? i.e. we have run 32 parts off a newly installed machine and performed capability using this gauge. Will the possible gauge error mean that the machine capability is better or worse? Interestingly, the dimension i stated before where we had 9.8% GRR is showing incapable on machine study.
Cheers
