Had the worst Monday in 5 years on the Haas last week

Last Monday I was running a job for a client in Detroit, 50 pieces of aluminum brackets. Everything was going fine until about the third part when I heard a weird chatter on the finish pass. I stopped the machine, checked the insert, and it looked fine so I kept going. About 10 parts later I realized my coolant nozzle had gotten bumped and was pointing the wrong way. By the time I fixed it, I had scrapped 7 parts total and had to reorder stock. My boss came over and just said 'you know that's $200 in material you just lost.' It was one of those days where nothing went right even when I double checked everything. Has anyone else had a simple mistake like a coolant line ruin a whole batch?

My buddy Mike did that with a titanium job once and scrapped 12 parts.

...I mean, are we really acting like 7 scrap parts and $200 is some kind of tragedy? I've seen guys scrap an entire shift's worth of work because they forgot to tighten a collet or something stupid. Coolant nozzles get bumped all the time, it happens. Unless you're running some crazy expensive material like Inconel or a really tight tolerance job, losing a few aluminum brackets is basically just a Tuesday. Your boss giving you grief over 200 bucks sounds like he needs to chill out, honestly. I'd get it if it was a pattern, but a one-off bad Monday? That's just how machining goes sometimes.
