Cutting speed of ball nose end mills - carbide.mmc.co.jp
The cutting speed of solid ball nose end mills is set according to the depth of cut, workpiece material, tool material and the diameter. Usually, the depth of cut is less than the ball nose radius. As seen in the image below, when machining on an inclination the maximum cutting speed changes according to the depth of cut.

Ball Milling - an overview | ScienceDirect Topics
Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.
