Can you hold
tolerance?

A Gage R&R measures how much of your error comes from the measurement system instead of the part. So we're going to run one — on you.

You'll see two bores. Call the larger one. We'll shrink the difference until you're guessing, slip in repeats to test your repeatability, and grade you like a first-article report. Takes about 90 seconds.

Spoiler: the spec is ±1 µm. Good luck.
