There are several factors to consider:

The rigidity of your machine, the rpm capability of the machine, the tool path (are you face milling or side milling, 2D or 3D). What is the quality level of your cutter and what is the coating of the cutter?

Hanita has a great booklet with tables for speeds and feeds with different styles of cutters, types of cut and materials. Their info may be online.

Also if your are interested in "High speed machining" and you have the necessary combination of machine, control, programming software, cutters, and tooling, you should go to www.creat.com and read the article entitled "Milling in the Hot Zone". The author Todd Shuet is one of the best authorities on HSM.
