 1.5" Dia High Speed hanging 6" | |
Im machining 6061-T6 cast aluminum and I have to use a 1.5 dia endmill hanging out 6" for clearance. The problem that I am having is I am taking a 3.5 DOC .075 off of the wall and the part is hanging out in the air. The endmill is not buried in part it is an outside cut. I am getting terrible chatter. running 250sfm @ .006 chip load. Any help out there. Do I need to increase my chip load or my SFM or both? |
