I heard cutting aluminum using fast feedrate with a double spiral carbide end mill is the way to go one like this http://toolinghouse.com/ESC1015U.aspx
What I saw was at 20,000 rpm 0.80 (1/16in) pass depth, at 100 in/min (1.6 in/sec) using the 1/4" double spiral carbide bit was beautiful parts. He said the faster the better cut finishes. Also most people run alum way slower than they think they should. They also use a very light cutting oil via a mister (oil here http://www.docs.citgo.com/msds_pi/639401001.pdf).
