Guide to Cutting Speeds and Feeds: Definition, Selection ...
For different operations, the definition of surface may vary. In drilling and milling, the surface is the outside diameter of the tool. In turning and boring, the surface can be defined on either side of the depth of cut (the starting surface or end surface). Cutting speeds are expressed in feet per minute (imperial) or meters per minute (metric).

Use a high-temp. coating designed for hard milling or high-temp. alloys. Use a light width of cut, typically between 25-40%. Use a light depth of cut, usually between .005"-.015". Use a light feed per tooth, usually less than the T-land width (.003"-.006") Good air blast should be used – no coolant (thermal shock)!

Introduction to Milling Tools and Their Application
Milling is done using a cylindrical milling tool mounted in a milling tool holder that is then mounted in the tool spindle on the machine. End Mills End mills are the most common milling cutters. End mills are available in a wide variety of lengths, diameters, and types. A square end mill is used for most general milling applications.

SFM to RPM [ Easy Guide to Surface Speed / SFM in Machining ]
On a milling machine, the cutter spins and the work remains stationary. Not only that, but there are usually multiple cutting edges or flutes on a typical endmill. The goal of surface speed is to provide a single quantity that can help determine the best spindle rpm for every cutter type, no matter whether it's on a lathe or mill.

How do you calculate spindle speed? - AskingLot
For turning applications we do not need this formula since Spindle Speed is usually given in Constant Surface Speed (CSS), which uses SFM value directly. But if you still want to use RPM formula, then diameter value is the actual diameter of work piece. Calculating Spindle Speed (RPM): RPM= 12 x SFM 3.14 x Diameter
