A foreman in a Cincinnati shop told me 'speed is just expensive scrap waiting to happen' after I crashed a spindle.
He said it while we were looking at the $8,000 part I'd just turned into a paperweight, and now I run my first piece at 50% feed every single time, no matter how much the schedule screams.
Rushing a job always ends up costing more scrap. We had to push a batch of aluminum parts last month and the reject rate tripled. People cut corners, skip checks, and suddenly you're remaking half the order. The extra material waste alone killed our margin. It's never just the overtime pay, it's the hidden cost of fixing mistakes.
