Hi Guys, i could use some wisdom.
So, I am making these parts, a lot of 3/16" end-mill stuff in 6061.
I have tried Aluma-power 3 flute polished end mills, and swift tool 45 Degeree helix end mills, also the merlin 5 flute GXMD5 with chip load at .001" per flute. 40 IPM on the 5 flute, it made a dozen parts before it scattered.
I am dying of old age.
14" per minute at 8K RPM. .070" DOC.
Anybody know if I could do better, maybe with HSS?
I can afford to rough, and then clean the slot to .1895 with a finish, if that get's me away from 14" per minute, long run...
Thanks,
Mark
