Abstract:

In this paper,the influence of axle cutting force and torque on dynamic behaviour is researched in the process of drilling.The 3-D tetrahedron finite element equations for drill bit with complex section are derived.Finally,the influences of cutting load on dynamic behaviour of drill bit are given.

Key words: cutting load, drill bit, dynamic response
