It don't mean a thing if it ain't got that ping.
It's a fun little beast.metrology
I've been in a CMM job for about 6 or 7 years. We have no metrologist, i.e. we are the metrologist. The science of measuring is pretty fascinating. I try not to think about it much outside of my day job but it's burned into my head at this point. You have to dig into the theory to be 100% certain with your results. Make them bulletproof and able to stand up to any amount of scrutiny.
The difference between being curious about the theory and process behind measurement makes a huge difference in actually getting highly accurate measurements. Any guy can stick a "tape measure" on something but I'd rather trust the results from a guy who knows how to use one three different ways.
