| Abstract: |
| Based on the analysis of the system structure, information flow path of the flexible machining device, we have built up the precise dynamic model of mechanical-electronic systems of the machining center, and developed the hardware to realize the real-time identification of parameters of the models. It is a strong base both for building up a real-time condition monitoring, fault diagnosis and prediction system and for getting rid of the influence of the changeful machining mode and the factor of time-varying in the FMS environments. |
