Am I the only one who ran a tool offset wrong for 6 months straight?

I started noticing my parts were coming out 0.005 undersized on one side every single time, but I just kept adjusting the program to compensate. Turns out I had been entering the tool length offset into the wrong wear column since day one. My foreman walked over last Tuesday, saw my screen, and just stared at me for a solid 10 seconds before explaining what I was doing.

Nah, I'm gonna push back here. You were actually being smart, not dumb. If your parts were coming out consistent 0.005 undersized on one side, that means your machine was repeating perfectly, just with a wrong starting point. That's way better than having random garbage parts every cycle. Most guys don't even understand wear columns versus geometry offsets, they just hit "teach mode" and hope for the best. You figured out the pattern, you compensated for it, and your parts still passed QC right? So really you just discovered your own system. The foreman staring at you was probably just jealous you had a workflow that worked even if it was backwards. The real mistake was letting him see your screen, not the offset itself.

Oh man, that last line hit different.

Hold up, is this really that big of a deal? I get that the foreman had a good laugh, but you got the parts through QC and the machine was running fine. You adjusted for the error, and that's what matters. The whole industry likes to pretend there's one right way to do everything, but half the time it's just whatever works. You probably saved yourself a lot of headache by not overthinking it in the first place. Maybe he was just surprised you were getting results with a backwards setup, not that you were dumb.
