In this paper,a fault tree of CNC hydraulic systems is developed based on fuzzy fault tree.The membership matrix is established by statistic data and then the membership degree of fault principle is obtained.Further, the fault reason is deter-mined by maximum membership degree law.The proposed method improves the efficiency of fault diagnosis and also provides a new reasoning method to design the fault diagnosis expert system.
