    They can be used for both plant and test mill data. The cumulative grinding rate through the size of interest is the identical parameter as the ball mill grinding rate calculated from the functional performance equation. Its maximization is the technical optimization criterion for ball sizing studies. High-performance carbide ball end mills are designed to last longer and create a finer finish when used in their recommended, first-choice materials than general purpose ball end mills. They are used in production milling. Finishing end mills create a finer finish on the workpiece than roughing and roughing/finishing end mills.
