GWizard has a builtin HSM calculator: An HSM cut in 6061 aluminum. The example cut being shown is a 1/2″ endmill in 6061 aluminum, 10% radial engagement as we've been talking about, and a full 1″ depth of cut. With an HSM toolpath that guarantees no corners will be cut, we can run 6747 rpm at ipm feedrate. That's a HP cut.

The process of ball milling and the materials that compose planetary ball mills are highly complex, and the existing research on the change in ballmilling energy is not mature. The theoretical model of a ball mill was established for the first time to simulate the motion, collision process, energy transfer, and temperature change of small balls during the ballmilling process. Furthermore, by ...

While adding a 5 th flute to a 4 flute tool theoretically gives you 25% more material removal per revolution with an appropriately increased feed rate, feeding the tool that much faster may overload the tool. The 25% increase in material removal is more likely closer to 1015%, given the tool is exactly the same in all other specifications.
