I am just entering the fascinating world of machining, for me as a hobby, and have questions regarding feeds and speeds for face milling of 6061 T6 Aluminium plate.
My mill is a workbench mill with 500W DC motor (LMS 4190 HighTorque MiniMill). I would be using a 2" Face Mill on R8 3/4" holder, with 5 ZCC APKT 1604 33 LH YBG101 carbide inserts made for Aluminium.
To calculate my feeds and speeds should I assume:
600 SFPM
0.003 IPT
I noticed that during the milling sometimes a chip would get pressed back into the surface of the stock, or make an ugly scratch. Now, that happened when I tried to use some cheap inserts which had some gold color coating. Probably totally unsuitable for Aluminium. With better inserts, I am hoping this won't happen. Comments?
