Abstract

In this study, we study the modal parameters and the vibration mode through analyzing the dynamic characteristics of the modal test of the key components and understanding the inherent characteristic of the whole structure of the CNC milling machine system. Based on the hammering method, the top 10 modal parameters of the CNC milling machine below 1000 Hz are obtained by the modal test. Through analyzing each vibration mode, the weak modals and the weaknesses which have great effect on the machine dynamic characteristics are determined, to provide a reference for improving the dynamic design of the machine structure.
