### Surface feet per minute - Wikipedia

When the SFM is known for a specific material (ex 303 annealed stainless steel = 120 SFM for high speed steel tooling), a formula can be used to determine spindle speed for live tools or spindle speeds for turning materials. In a milling machine, the tool diameter is substituted for stock diameter in the following formulas.

### Speeds and feeds - Wikipedia

The phrase speeds and feeds or feeds and speeds refers to two separate velocities in machine tool practice, cutting speed and feed rate. They are often considered as a pair because of their combined effect on the cutting process. Each, however, can also be considered and analyzed in its own right. Cutting speed (also.
