The </p> <p>motion of a boring bar is frequently influenced by force modulation, i.e. </p> <p>the dynamic motion of the workpiece related to the residual rotor mass </p> <p>imbalance influences the motion of the motion of the boring bar via the </p> <p>relative dynamic motion between the cutting tool and the workpiece. </p> <p>Second-order cyclostationary analysis of the non-stationary stochastic </p> <p>motion of a boring on a lathe is carried out and compared with the </p> <p>conventional spectrum estimation method of the power spectral density. </p> <p>It is observed that the periodic nature of this dynamic motion suits well </p> <p>in the cyclostationary framework because of the rotating motion on the </p> <p>lathe. Also, it is found that cyclostationary analysis contains the time </p> <p>information in the metal cutting process and it can provide insight on the </p> <p>modulation structure of the frequencies involved in the boring operation. </p>}, number={3}, publisher={MUSA YILMAZ}
