I work at a job shop and am running a haas tm-1 with a 4000 max spindle. I believe its a 2005 model. There is only 4 employees total and I really gotta figure things out on my own. I feel like sometimes im pushing my tools too much or not enough etc.
Anyways I got a (probably china) .500 carbide endmill with about an inch of cutting flute. Im using 200 SFM and .002 feed per tooth and came up with 1528 RPM and 12.0 feed. I am side milling A-2 with a height of .750 and only taking .030 at a time. It is in a brand new er32 collet and im chucked right above the flutes so about 1.1 sticking out. For some reason when my parts get above .500 in height (in this case .750) I get crazy chatter and it sounds awful. This endmill should be able to take this cut? Am I doing something wrong? Side milling is a pretty basic operation for squaring up the last two sides. ANY advice at this point is appreciated.Thanks in advance.
