Shoutout to the old timer who said to slow down my feed rate on aluminum

I was running a 7075 part at 80 IPM and burning up end mills every 30 minutes until I finally listened to him and dropped it to 45 IPM, and now a single tool lasts me a whole shift, has anyone else had a similar wake-up call on feeds?

Ha, nah I actually went the opposite way and bumped mine up to 120 IPM on 6061 and got better results. Guess it depends on the machine and if you're okay with a rougher finish.

Damn, you might be onto something. I was all about slow feeds but this got me thinking.

Used to run slower but @max_schmidt77 has me reconsidering.
