The basic geometrical components of the ball part of a ball end mill are depicted in workpiece coordinates, OXYZ, as shown in Fig. 1 (a). The ball part is machined using a grinding wheel, as shown in Fig. 1 (b) and (c). The rake face and the flute surface are generated by the side face and the revolution surface of the grinding wheel, …
The process of ball milling and the materials that compose planetary ball mills are highly complex, and the existing research on the change in ball-milling 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 …

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
