2 topics across all disciplines.
Measurement and gauging
Micrometers, height gauges, CMMs and functional gauges compared, why the 10 to 1 rule governs gauge choice, what measurement system analysis is really asking, and why temperature quietly ruins precision work.
Checking fixtures and functional gauges
What a checking fixture does that a CMM cannot, how a functional gauge turns a GD and T callout into a part that either fits or does not, why gauge tolerance eats the part tolerance, and where scanning belongs.
