A new mathematical model for grinding the ball part of a ball end mill is proposed. The complete process for manufacturing a ball end mill is formulated, including processes such as modeling the rake and clearance faces. The helical flute surface of the ball end mill is analytically calculated and verified by means of simulation and experiment.

Mathematical models, which link the external signals of ball mill with its internal parameters, were established to predict the internal parameters of ball mill. Experimental results showed that the mathematical models could directly predict the internal parameters of ball mill …
