C34 Examination of Method of Quantification of Dynamic Characteristic Parameters of Tooling System Based on Impulse Response(Evaluation of machine tool performance)
Details
In this study, the new quantification method of the dynamic characteristic parameters of the tooling system is proposed, and then, its validity and utility are examined based on the experiment and the theoretical analysis. By extracting of the single mode element of vibration waveform and correcting the discretization error, the dynamic characteristic parameters can be quantified correctly compared with the conventional method. From the applied results, the influence of the difference in the structure on dynamic stiffness of tooling system can be explained based on the physical parameters such as equivalent stiffness and equivalent damping coefficient.
