The milling process begins by inserting the workpiece into the CNC machine's work surface or holding device. This is followed by placement of the milling tools to the machine's spindle. The directionality of the milling process can be either horizontal or vertical depending on the requirements programmed from CAD.

This mechanical operation consumes the energy, and size reduction is merely a result of this energy consumption. This viewpoint is reasonably valid for tumbling mills where energy input tends to be constant and the proportion of the energy that is usefully consumed in particle breakage is low (<10%).

Size reduction of solids involves creating smaller mass units from larger mass units of the same material. To bring this about, the larger mass units need to be subjected to stress by the application of force. Three types of force may be applied, compression, impact and shear. Compressive forces are generally used for the coarse crushing ...
