Gage R&R Study Difficulty

Hi folks,

I thought I'd reach out on here to receive some advice. We're currently doing gage R&R studies on a new turbine blade that we're developing.

We have acceptability at around the 30%-mark. Most features easily achieve this however we're having difficulty on the blades firtree pressure flanks. This is down to the tolerance attached with this feature, which is +/-0.007mm.

This only allows for around a 2micron variance. Is there a way we could prove our repeatability without going down the gage R&R route?

Cheers guys
