Milling spindle speed for aluminum??? - RC Groups

Feb 09, 2007 · Dave, from using my own mill I found that you can really feel when an end mill is happy with your feed rate. As long as the rotational speed is in the ball park for the size of cutter in question you'll see what I mean. Too slow and it doesn't seem to take the cut as nicely. Too fast and the machine will start complaining.

Critical speed - Wikipedia

In solid mechanics, in the field of rotordynamics, the critical speed is the theoretical angular velocity that excites the natural frequency of a rotating object, such as a shaft, propeller, leadscrew, or gear.As the speed of rotation approaches the object's natural frequency, the object begins to resonate, which dramatically increases system vibration.
