This old timer at a trade show in Cleveland gave me a tip that saved a job

I was at a machine tool show maybe two years back, looking at a new Haas VF2, and this guy next to me, had to be in his 70s, just starts talking. He saw me frowning at a print for a tricky aluminum part with thin walls. He said, 'Kid, for that, run your finish pass at 95% of your programmed feed, not slower. Lets the tool pull out of the cut cleaner.' I tried it the next Monday on a job that was giving me chatter, and it worked perfectly. Has anyone else run into a situation where going a little faster on the finish actually made a better part?

Oh yeah, had the same thing with a stainless part. Bumped the speed up a touch and the finish came out way cleaner.

Man, that reminds me of when I tried cutting aluminum too slow and just made a mess.

Try a tiny bit of WD-40 next time, works wonders.
