between vertical mills and ball mills arises from differences in the frequency and energy intensity of ball collisions. The higher efficiency of the vertical mills is due to the higher frequency of lower energy impacts and, by the same token, lower frequency of higher energy impacts when compared to conventional ball mills (Mazzinghy et al., 2013).
wear has proven sufficient and it has been utilized as a means of tool wear prediction. Replicating the same machining con-ditions, in overlap [48] and in mixing up and down milling [49], in case of a different machine tool, additional studies have also correlated tool wear with electrical current [31].
