Study on an autonomous numerical control system based on embedded technology

The research focuses on machine tool initiative perception and self-adapting to complex and dynamic manufacturing environment using embedded technology, multi-information sensing and fusion, and combined intelligent information processing. The architecture of autonomous numerical control system based on embedded system is presented according to conceptual model of autonomic management system and idea of hierarchical intelligent control. There are three layers in the architecture and function of every layer is introduced. The paper also gives an implementation of the system composed of hardware and software modules. When the system was used to control three dimension milling machine in the lab, experimental results have indicated that it has good reliability, stability, definite precision and adaptability.
