As a finite element simulation software,the cutting process of a new modular bit drill is simulated by Ad-vantEdge.The simulation data is analyzed by the range method,and it is concluded that the depth of the positioning hole in the cutting process has the greatest influence on torque,temperature and mises stress,fol lowed by the diameter of the posi-tioning hole,and the diameter of the circular arc of the chip module of the tool bit module has the least impact.The size of the positioning hole diameter has the greatest influence on the cutting force,followed by the arc diameter of the chip groove of the tool head module,and the influence of the center fixed positioning hole depth is the least.The optimal structural pa-rameters of the new modular bit drill with a diameter of D,=32mm are obtained,and the diameter of the chip groove of the bit module is 7mm,the diameter of the positioning hole is 5mm,and the depth is 4.5mm.
