I am cutting a 5/32 radius on a bunch of Alum parts. I burnt the one that I have now, which may have been slightly dull already. Tool is a .220 minor diam, .77 major diam. 4 flute HSS uncoated.
I just wanted to make sure I was running this right. I usually try to stay on the conservative sides of things, we are a tool room, not a production shop.
Heres what I'm using:
300 SFM = 1517 RPM
Feeds: .002" CPT (12 ipm)
Depths: .07, .09, 0.11, .13, .14, .145, .150 x2
Those are in inches, I only go down to .150
Any recommendations?
