In the system design, the Unified Modeling Language is employed to illustrate interactions of the objects required in the system. The developed system consists of a set of smart distributed control nodes connected one by one through the IEEE-1394 bus. Each smart node contains four modules, i.e., an IEEE-1394 interface module, a digital signal processor module, a field-programmable gate array module, and a digital-to-analog converter module. It accomplishes its own control task and coordinates with the others through information exchanges, sampling sensor signals, and controlling actuators. A scheduled communication protocol is proposed according to the criteria in terms of bounded time delay and guaranteed transmission. Time delays arising from data processing and message transmission are analyzed. A platform is built, and experiments are conducted to demonstrate the capabilities of the developed distributed control system for real-time communication and synchronous tracking control, which are required for multiaxis applications. The results verify the feasible application of the IEEE-1394 bus to distributed motion control.

On a numerical method for simultaneous prediction of stability and surface location error in low radial immersion milling / Ding, Ye in Transactions of the ASME . Journal of dynamic systems, measurement, and control, Vol. 133 N° 2 (Mars 2011)

Titre : On a numerical method for simultaneous prediction of stability and surface location error in low radial immersion milling Type de document : texte imprimé Auteurs : Ding, Ye, Auteur ; LiMin, Zhu, Auteur ; Zhang, XiaoJian, Auteur Année de publication : 2011 Article en page(s) : 08 p. Note générale : Systèmes dynamiques Langues : Anglais (eng) Mots-clés : Machining  chatter  Matrix  algebra  Milling  Milling  machines  Stability Index. décimale : 629.8 Résumé : This brief proposes a numerical approach for simultaneous prediction of stability lobe diagrams and surface location error in low radial immersion milling based on the direct integration scheme and the precise time-integration method. First, the mathematical model of the milling dynamics considering the regenerative effect is presented in a state space form. With the cutter tooth passing period being divided equally into a finite number of elements, the response of the system is formulated on the basis of the direct integration scheme. Then, the four involved time-variant items, i.e., the time-periodic coefficient item, system state item, time delay item, and static force item in the integration terms of the response, are discretized via linear approximations, respectively. The corresponding matrix exponential related functions are all calculated by using the precise time-integration method. After the state transition expression on one small time interval being constructed, an explicit form for the discrete dynamic map of the system on one tooth passing period is established. Thereafter, the milling stability is predicted via Floquet theory and the surface location error is calculated from the fixed point of the dynamic map. The proposed method is verified by the benchmark theoretical and experimental results in published literature. The high efficiency of the algorithm is also demonstrated.
