A comprehensive guide for Speeds and Feeds calculations and considerations for CNC milling. The website offers also more info and resources you can explore.
Note:
Personally I think that the G-wizard they offer is too expensive (and will be even more if you keep subscribing to it). Since all the information which the calculator is based upon came for free through the web to the developer, I think it should be offered for free also. But..that's just my opinion.
