Abstract: According to the numerical control system of real time property, embedded characteristics and for the special needs of specific manufacturing technology, this paper puts forward the a construction method of numerical control system for aspect-oriented orthogonal structure. The system structure designed includes basic component, aspects component and connector as the core elements constitute hardware control center and time control center. Hardware control function from the basic components and connectors, time control function is composed by the time aspect component and connectors. The components correlation in time between different threads is realized by aspect-oriented component crosscutting. Analysis results show that this method is beneficial to the system performance analysis and assembly application, and easy to the reconstruction of the numerical control users.

Key words: orthogonal structure, aspect-oriented, numerical control system, component
