Study on tool wear estimation for small diameter ball end mill milling …

2. In the small-diameter ball end mill, because the cutting edge has a curvature, the cutting force linearly increases in both the axial direction F Z and the rotational direction F X Y as tool wear progresses steadily. 3. Points 1 and 2 are valid even if the cutting position of the tool changes. 4.

Ball Milling

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
