Introduction to Milling Tools and Their Application - MachiningCloud
Ball end mills produce a radius at the bottom of pockets and slots. Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket.

Method of assessing ball mill health - SAGMILLING.COM
A ball mill grinding efficiency above 80% is considered "good"; the measured efficiency of 95% is "very good". This suggests that the ball mill is functioning well, and would not see any substantial benefit from further optimization.

Geometric Simulation of Ball-End Milling Operations
In this paper, B-rep solid modeling techniques are used to deal with geometric modeling issues encountered in ball-end milling simulation. The precise B-rep model of the cutter swept volume is developed using advanced sweeping/skinning techniques. Semi-finishing operations are simulated by performing consecutive Boolean operations between the updated part and swept volume. The instantaneous ...
