Vent: my probe touched off on the fixture and ate a $90 end mill on Monday morning
I was running a batch of 6061 brackets on the Haas and rushed my setup after a long weekend, so I never rechecked the work offset. The tool drove straight into the steel fixture plate at 6000 rpm and snapped the end mill, plus dinged the plate I just had ground flat last month. How do you all keep from making that same dumb mistake when you are trying to get parts out the door fast?

A $90 end mill and a ground plate in one morning is a rough start to the week. When you say you rushed the setup after the long weekend, was it the G54 you skipped checking or the tool length offset? I ask because those are two very different habits to build. A lot of shops I know force a dry run above the part with the feed cranked way down before any tool ever gets near the fixture, and it catches this exact thing. Do you have a written setup sheet you check off, or is it all in your head? If it lives in your head, that is probably the real problem, not the long weekend.
