Abstract
This paper exposes the complete procedure of suppressing the chatter and how to realize it on a direct-drive CNC hobber. In a series of experiments, we discovered the phenomenon that vibration energy was centralized at a natural frequency of the machine gradually during the chatter occurred. Based on the phenomenon and the theory of regenerative chatter, a multi-degree of freedom model about the chatter of machine is built. According to this model, the way to identify chatter frequency and weak component is proposed. Taking the bobber spindle system as an example, several key steps are introduced: building optimization model of spindle, reducing the modified parameters based on sensitivity of anti-chatter and the optimization algorithm. Optimal result of hob spindle system is provided finally.
