I know a CMM with a scanning head can do this reliably, but what other methods are used and how accurate are they? Will they pass a Gauge R&R @ 10% or less?
Thanks.

Yes I agree talk to your customer and find how they are going check your work. I have heard so many nightmare stories about differing methods of QC measuring leading to you measure it one way, it is good. They measure a different way... and it ain't.
I know some guys are thinking this makes me look like I don't know my ass from my elbow. I look at this way if I where the customer and the shop called with that question it would indicate a couple things. Shop wants give me what I want, pride aside, they want me to be happy and provide me with right part first time.
