Shoutout to the old guy at the tool crib who caught my feed rate mistake
I was running a batch of 304 stainless parts on our Haas VF2 and kept burning up end mills after about twenty pieces... thought it was just bad tooling. The senior operator, Frank, watched my setup for two minutes and asked why my feed was so high. Turns out I had the decimal in the wrong place in my program for six months, running at 10 inches per minute instead of 1.0. I was just copying an old program from a previous job and never checked it. Has anyone else had a simple typo in a program cause a ton of wasted tools?

Frank's a legend for spotting that, been there with a decimal typo trashing carbide like it was paper.

My old boss made me read programs out loud.

Oh man, @sarah_johnson46, that is the worst. I had a manager who did the exact same thing. He said it helped him "catch errors," but it just felt like a weird power move. I had to sit there and read line after line of code like a kid in a reading circle. It was so awkward and a huge waste of time. I never understood what that was supposed to prove.
