A ball nose end mill's Effective Cutting Diameter (D eff) differs from its actual cutting diameter when utilizing an Axial Depth of Cut (ADOC) that is less than the full radius of the ball Calculating the effective cutting diameter can be done using the chart below that represents some common tool diameters and ADOC combinations or by using the traditional calculation (see Figure 2)

Ball Mills are generally used to grind material 1/4 inch and finer down to the particle size of 20 to 75 microns To achieve a reasonable efficiency with ball mills they must be operated in a closed system with oversize material continuously being recirculated back into the mill to be reduced Various classifiers such as screens spiral classifiers cyclones and air classifiers are used for classifying the discharge
