How accurate is 3D scanning for reverse engineering aerospace parts? Checking before we build CAD.
We need to reverse engineer a small aluminum bracket from an older aircraft. It has a deep pocket and a few holes held to about 0.05 mm.
Our scan looks clean, but I don't trust it yet on those features.
Where is a scanner good enough, and where do you still use a CMM?
I read that scan data can drift from nominal until the datums are set right, but I'm not so sure. How do you check the scan before anyone starts modeling?
