Took me 4 hours to figure out a .001 offset issue

I was running a job on our old Haas VF-2 last Tuesday and kept getting parts .002 over on the bore. Turned out my G41 comp table had a typo from the previous operator - one line said .003 instead of .002. Four hours of re-cutting parts and chasing my tail before I caught it. Has anyone else had a tool offset typo cost them a whole shift?

Oh man, the "typ in the comp table" part hit me hard. I had this one time where I was chasing a .005 shift on our Fadal for like 3 hours. Turned out the guy before me had a .010 radius in the tool table for a .125 endmill. He just typed it in wrong and never said anything. I was literally about to pull the spindle apart thinking the bearings were shot. The worst part is when the fix is something that dumb and you spent half a shift on it. Makes you feel like an idiot but honestly its just part of the trade. Now I always check the tool table before i even start the program, saves me from that headache again.

God I felt that in my soul lol. Three hours chasing a ghost because someone fat fingered a number. I had one where the guy before me left a decimal point out on a feed rate and my machine sounded like it was going to launch itself through the roof. Its always the stupid little crap that gets you too, not the big obvious stuff. Makes you want to scream but hey at least you know for next time lmao. Checking the tool table first is the only way to keep your sanity in this gig.
