That time I bumped my feed rate by 25% on a Haas VF-2 and finally stopped fighting tool chatter

I was running a 1/2 inch endmill in 6061 aluminum and getting that annoying chatter sound on the corners. After reading some old forums and trying different speeds, I just cranked the feed from 30 IPM to 38 IPM on a test part last Tuesday. The chip load changed just enough to dampen the vibration and the surface finish came out mirror smooth. Has anyone else had luck breaking out of the 'slow and safe' mindset and actually going faster?

I mean, I usually just panic and hit the feed override. Classic me.

Jumping on this is kinda like when you find out your windshield wipers work better at high speed in a downpour, right? The instinct is to slow down and baby it, but sometimes the chaos works in your favor if you just commit. Good discovery.
