Hey everyone,
I've got a 1" dia x 6" length 4 flute HSS end mill that I am using to finish a 2" long bore that is 5" deep in an aluminum part and I cannot for the life of me get it to stop producing a rifle barrel finish from all the chatter.
I've tried every combination from 130-315 sfm, 0.002-0.005 ipt, and 0.005-0.030 step over.
The "best" results which are still completely unacceptable seem to be with high sfm, low chip load, and light step over which seems to go against the general consensus of wanting to load up the cutter.
Any thoughts on other cutting conditions to try running?
