In our second model we calculated the movement of balls in the resting suspension. In the third modelA mathematical model for simulating and manufacturing ball,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.
