Journeyman on my shift said he never checks his offsets after a tool change, and I can't stop thinking about it
Had a talk with the journeyman who runs the lathe next to mine at our shop in Dayton, and he said he hasn't touched his wear offsets in 3 years unless a part fails inspection. That hit weird because I check mine after almost every tool change, sometimes twice on a 12 hour run, and I thought that was just what you do. He said he trusts his setup sheets and his touch-offs, and all that rechecking is just me being nervous, which honestly stung a little. Now I'm second guessing whether I'm wasting time or whether he's just been lucky on the parts he runs. Any of you guys actually run without touching offsets, or is that a good way to scrap a whole batch?

I used to do the same thing, check wear offsets every couple hours like clockwork, and my lead guy told me basically the same thing your journeyman did. What helped me was meeting in the middle, now I just check after the first part on a new tool and then leave it alone unless the finish starts looking off. Last month I caught a boring bar drifting about .003 on a 200 piece run because I stopped and looked at part 10, saved the whole batch. So the checking is not nerves, it is just knowing when it actually matters instead of doing it every hour on the hour. Your journeyman is not wrong that trusting a good setup sheet works, but he has probably just never had a bad insert batch bite him yet.
