文摘Using time domain data, orbital plots, and spectrum analysis of drill point displacement, cutting force and torque signals, the initial penetration in drilling is experimentally investigated. The mechanisms of drill wandering motion are analyzed by means of three principles of selfexcited vibration, i.e. the regenerative principle, velocity component principle and mode coupling principle.
