Caught my tool offset being 0.015 off on a 10 part run

I noticed a guy down the hall kept getting scrapped parts from his face mill, turned out he was zeroing off the wrong surface on his probe routine. I showed him how I use a 1-2-3 block to set my Z every time, and his last batch came out clean. Anyone else run into people skipping basic setup steps like that?

Wrong surface on his probe routine" - maybe he had a reason for that setup you don't know about. Sometimes a 0.015 offset is just chasing a temperature swing or a worn insert, not a setup mistake.

Did you catch that post from a few weeks back where a guy had a 0.020 offset because his machine was warming up? I think @joseph_torres makes a solid point that a 0.015 move isn't always a setup error. Sometimes you're just chasing a temperature swing or a worn insert like he said. I've seen guys spend hours trying to dial in a part only to realize the coolant was off and the size was drifting. So yeah, calling it the wrong surface might be jumping to conclusions.
