I finally stopped chasing the perfect surface finish at a job in Newark

Had a run of 316 stainless parts last month where I kept bumping the feed rate trying to kill every last tool mark. Customer complained about a tiny waviness, so I went full polish mode, ruined two inserts, and the finish got WORSE. A guy from the next bay said "you're fighting the material, not the machine" and told me to leave the last pass at a constant chip load. I backed off to the original speeds and just swapped to a wiper insert instead. Has anyone else found that chasing perfection actually makes the surface worse, or am I just too picky with my finishes?

Same thing happens with cooking honestly. You keep adjusting the heat and stirring to get that perfect sear, and the meat just turns chewy and grey because you never let it sit. Sometimes the best move is trusting the basic setup and letting the process work instead of poking at it every five seconds.

Ask @jake_torres68 how you actually know when you've hit that sweet spot, though. Like with steak, you check the temp or the feel, but with a sear it's all visual and sound. Same with a codebase or a project, how do you tell the difference between healthy settling and something that's just stuck and needs a nudge? I've burned dinner both ways, too much trust and too much fussing, so I'm genuinely curious where the line is for you.
