Phil I don't know what exactly you mean different geometry, but if you are asking have I milled other parts with this endmill then yes i did and there seems very similar problems with it. Because of this chatter I prefer using smaller endmill 6mm in diameter that gives no chatter, but for large parts you can't get that removal rate. That part is now half made and waiting for its time to be flipped over for other side to complete.
