The impact energy of the milling balls in the normal direction attains a value of up to 40 times higher than that due to gravitational acceleration. Hence, the planetary ball mill can be used for high-speed milling. Schematic view of motion of the ball and powder mixture.

Feed per Revolution Travel of workpiece during one revolution of milling cutter. It is expressed as mm/rev. and denoted by f(rev). Feed per Unit of Time Feed can also be expressed as feed/minute or feed/sec. It is the distance advances by the workpiece in unit time (fm). Above described three feed rates are mutually convertible. (fm). = n x f(rev).

Ball mills can be designed to operate continuously (fed at one end of the system and discharged at the other), or on a batch basis for smaller, or intermittent volumes. They can also be operated either on a stand-alone basis ('open-circuit grinding') or in conjunction with a classifier which returns oversize product to the mill for further grinding ('closed-circuit grinding').

 · Mechanics and dynamics of cutting with helical ball end mills are presented. The helical ball end mill attached to the spindle is modelled by orthogonal structural modes in the feed and normal directions at the tool tip. For a given cutter geometry, the cutting coefficients are transformed from an orthogonal cutting data base using an oblique cutting model. The three …
