Inaccurate and not timely fault diagnosis of NC machine may bring huge economic loss to manufacturing companies. Therefore, fault diagnosis and maintenance of NC machine is one of manufacturing industry research hot spots. On the basis of analyzing the characteristics of NC machine, a fault tree model of the CNC machine main parts is proposed in this paper. Based on this model, a fault diagnosis system using fault tree analysis method is developed. This system has several advantages, such as last diagnosis velocity, accurate diagnosis rate. Intelligent analysis and diagnosis of the NC machine fault can be realized effectively.
