  • The dynamic performance of an ultraprecision fly cutting machine tool (UFCMT) has a dramatic impact on the quality of ultraprecision machining. In this study, the dynamic model of a UFCMT was established based on the transfer matrix method for multibody systems (MSTMM). In particular, the large-span scale, flow field mesh model was created; and the variation in linear and angular stiffness of journal and thrust bearings with respect to film thickness was investigated by adopting the dynamic mesh technique (DMT). The dynamic model was proven to be valid by comparing the dynamic characteristics of the machine tool obtained by numerical simulation with the experimental results. In addition, the power spectrum density estimation method was adopted to simulate the statistical ambient vibration excitation by processing the ambient vibration signal measured over a long period of time. Applying the dynamic model, the dynamic response of a tool tip under ambient vibration was investigated. The results elucidated that the tool tip response was significantly affected by ambient vibration, and the isolated foundation had a good effect on vibration isolation.

Abstract: 

The dynamic performance of an ultraprecision fly cutting machine tool (UFCMT) has a dramatic impact on the quality of ultraprecision machining. In this study, the dynamic model of a UFCMT was established based on the transfer matrix method for multibody systems (MSTMM). In particular, the large-span scale, flow field mesh model was created; and the variation in linear and angular stiffness of journal and thrust bearings with respect to film thickness was investigated by adopting the dynamic mesh technique (DMT). The dynamic model was proven to be valid by comparing the dynamic characteristics of the machine tool obtained by numerical simulation with the experimental results. In addition, the power spectrum density estimation method was adopted to simulate the statistical ambient vibration excitation by processing the ambient vibration signal measured over a long period of time. Applying the dynamic model, the dynamic response of a tool tip under ambient vibration was investigated. The results elucidated that the tool tip response was significantly affected by ambient vibration, and the isolated foundation had a good effect on vibration isolation.
