Abstract

Many cutting errors cause micro drills breakage in a kind of complex stress state under loaded by thrust, torque and radial force. It is important to research the breakage mechanism of micro drills and prevent from breakage during micro drilling. In this paper, a 3D micro drill is modeled by using the Pro-Engineer software. The maximum load and the stress distribution are calculated by using MSC.FEA software, which is a kind of finite element analysis(Abbreviated as FEA)method. The fracture mechanism of micro drill with different diameter under one or more loads is discussed, and the maximum axial force and maximum torque of the micro drill bit under the complicated working condition are obtained. A large number of experimental results can be used for practical engineering reference.
