I machine quite a bit of aluminum. Generally, across the board, I’d keep you surface Speed at 800-1,000 SFM. For feed, I personally shoot for .0007” IPT (inch per TOOTH) per Rev. on the 1/16” tool. I don’t run anything in aluminum smaller than that, but if I did, I would simply halve the feed.
You didn’t mention you axial and radial DOC. My answer is based on an axial of 1 x Diameter and a Radial of .75 x Diameter.
Mileage will vary and others may chime in with slightly different formulas that work for them. This is what works for me.
Your mileage will vary by several factors: your spindle TIR (runout), tool geometry and your decision on the topic of coolant being the most important…especially TIR. If your runout is .001” and your chip load is .0007”, you have a problem.
