My go to feeds and speeds for roughing aluminum are... Sometimes I push, sometimes not, but this is my starting point.
1/2 3 flute end mill
2020 sfpm ( 15,432 rpm)
.008 chip load (feed 370)
20% step over (.100)
200% axial depth (1.000) max
I was talking to a pretty experienced guy a while back who told me he was regularly at 800 inches per minute. Which got me wondering "what does he know that I don't?"
I've concluded that either he was trying to impress me with some Titan type numbers or his stepover is 10% or less, in which case what's the point? 800 ipm at 10% or 400 @ 20.
So, what is everyone else's go to high speed parameters? Discuss!
