Pro tip: I see a lot of folks ignoring their tool length offsets after a setup

I was running a batch of 500 aluminum brackets last week and kept getting a tiny burr on the bottom edge. My coworker in the next bay had the same issue. We finally realized we were both just trusting the tool setter and not actually checking the offset against the first part. A quick touch with an indicator showed we were off by about .002, which was enough to cause the problem. Anyone else double-check their offsets on the machine after setting tools?

Josephs26 is right about the scrap cut. I've started doing that on the actual machine table with a piece of the same stock clamped down. It lets you check the offset and also verify your workholding and feeds before the real part runs.

Always run a test cut on scrap material to verify the offset before starting the batch.
