The last time I cut aluminum I just used the feeds and speeds in Carbide Create and cut dry w/ dust collection (the Sweepy I used is a bit hazy now from the scratches).
Things which will help:
- use an endmill w/ a suitable coating (the coated ones in our shop are all suited to alu.)
- clear the chips
- set initial Z-axis height accurately
- rigid workholding
