I'm running a 1.25" three flute end mill (HSS / TiCN) in plain-old 6061-T6 Aluminum.
Is 590 SFM too much for HSS?
I ran a couple tests (slotting with 0.75" depth) in some scrap and came up with 590 (1800 rpm) 20 IPM (.0037 IPT).
The chips look great and clear the slot nicely. The finish is acceptable and the machine is happy.
I planned to slot at .0037 IPT, rough at .005 IPT, and finish at .002 IPT.
Will good HSS with TiCN hold an edge at 590 under these conditions?
