As a boot, this will go against, best practices, history and formulas. I am starting to question the tool speed of a mill and turning speed of a chuck, as it relates to quality of the finish.
Watching CNC equipment run and the finishes produced, what is common, they all use high rpms. That in mind, I have begun to up the tool and chuck speeds of my runs lately. Not extreme but starting at twice what is normally thought to be proper.
Knowing this adds heat and stress, I reduce the feed speed, and keep the cuts light. I am seeking a better finish as an end result.
So what are some the thoughts form the seasoned machinist that are here?
