Just realized I've been setting my tool offsets wrong on our old Haas VF-2 for months

Last week in the shop, I was running a batch of 304 stainless parts and kept getting a weird finish on the last pass. My lead, Dave, watched me for five minutes and pointed out I was touching off the tool to the part surface instead of the fixture plate, throwing the Z-axis off by like 0.015. I've been doing it that way since I started here in Grand Rapids and nobody caught it. Anyone else have a dumb habit they didn't know was wrong until someone saw it?

Nah @lilyf74, that 0.015 can totally scrap a part. It adds up and messes with your finish like the OP said. Gotta get those offsets right.

Honestly, is 0.015 even that big a deal on most jobs? Unless you're doing super tight tolerance aerospace stuff, that's probably still in spec for a lot of parts. Sounds like it was working fine for months.
