Best fit alignment for troubleshooting manufacturing processes?

Somethingidc 4 months ago

Can someone explain how a best fit alignments used to troubleshoot manufacturing processes?

Pros/ cons of best fit vs normal alignment?

I'm having a hard time understanding how using a best fit would help with troubleshooting over a normal alignment.

Please provide detail in explanations.

Thanks.

So basically by comparing differences in info given by best fit alignments to the features that are OOT to the actual datum alignment to print you see the deviation of the features from the actual datums as well as the deviation of the datums to the features- giving (like you said) the whole picture?

Yes, but with the caveat that the type of best-fit (least squares vs min/max) and depending which features have deviation and in which direction those deviations are, it will influence the results - as has already been mentioned by NinjaBadger and vpt.se.
