Finite element analysis software AdvantEdge FEM was used to study drilling processing of new drill head, and the finite element analysis model of drill head was established.By the orthogonal test and single factor analysis method,the change rule of the drilling axial force, torque and drilling temperature with the amount of drilling was explored. In order to verify the feasibility and accuracy of simulation analysis, the drilling experiment of CNC machining center was carried out. By comparing with the experimental data and the simulation data, the conclusion has good consistency.
