i think i have a chatter problem? i am machining a part that is 5.500" in diamater and 1.375" tall. my tool is a .375" carbide 2 flute with 1.75" loc.
(6061) now, my rough program came out great but when it did the final profile all the way around there is what looks to be chatter marks about halfway down the part. maybe .500" off the bottom and mayb .500" from the top? its only like .375" of ugly machining right in the middle of the part. is my tool dull in that area or ????
