Speeds and Feeds 101 - In The Loupe

With miniature tooling and/or certain materials the speed calculation sometimes yields an unrealistic spindle speed. For example, a .047" cutter in 6061 aluminum (SFM 1,000) would return a speed of ~81,000 RPM. Since this speed is only attainable with high speed air spindles, the full SFM of 1,000 may not be achievable.

Cutting Speed - Machining Doctor

In machining, the words "Speed", "Cutting Speed", "SFM" and "Surface Speed" all refer to the relative linear velocity between the tip of the cutting edge and the workpiece. The definition is the same for all machining operations turning, milling, etc. (Opposed to feedrate which has a different definition for different applications).

Fablab Feeds and Speeds Calculator

Cutting generates a lot of heat, making oil based coolant preferable. Many machining spindles require 2000 rpm or more, to provide adequate cutting torque, which means that you have to use relatively small diameter end mills in order to end up with surface speeds this low. If not using coolant, then max surface speed is 50 ft/min. Insulation
