| Abstract: | A general fault monitoring and diagnosis expert system for NC machine tool was built.The system allowed users to build the fault tree in an interactive way and the knowledge of fault tree was expressed as production rules.On this basis,forward and backward reasoning with the integration of information from multiple sensors was realized.The experimental results show that by the expert system,fault reasons can be diagnosed using information from multiple sensors and repair scheme is given.So the goal of fault diagnosis for NC machine tool is achieved. |
