Experiment-aided virtual prototyping to minimize tool-workpiece vibration during boring of large-sized structures
The paper presents the author’s method of solving the problems of vibration suppression during boring of large-sized workpieces by means of an innovative method of adjusting the rotational speed of the boring bar. It consists in selecting the spindle speed in accordance with the results of the cutting process simulation. The method includes identification of the model of the finite element method of the boring bar. The Root Mean Square (RMS) values of the time plots and dominant values of the peaks in the frequency spectra were obtained during the boring process. The effectiveness of the proposed attempt is demonstrated by the selected mechatronic design technique, known as Experiment-Aided Virtual Prototyping (E-AVP). The proposed method has been verified based on the results of experimental research.
