Abstract
The main purpose of the research of Machine tool fault diagnosis system based on WEB is to make the user of the machine tool equipment can quickly diagnose the fault reasons when machine tool goes wrong. And the user can find a way to solve the faults, through the system
we can effective shorten equipment’s downtime due to equipment faults. For machine tool manufacturers, they can reduce many small and easy faults due to expert diagnosis system, also they can reduce the number of maintenance people, reduce the after-sale technical support costs, the system can improve petitiveness of products.
This paper designed and realized a fault diagnosis expert system based on WEB services, the system can improve the efficiency of solving machine tools’ problems. And has an important effect to quickly restore production. This system uses the Java language, so it can run on many terminals in theory. The system can quickly solve the problem of malfunction of the machine tools. The system is divided into ordinary users and administrator users, they can go for different types of operations.
This paper is based on wuxi kaiyuan machine tool plant, at first it introduces the development history of fault diagnosis technology and expert system, lists mon machine tools’ information and fault types, then we study the structure of fault diagnosis expert system , different parts of the expert system and their functions, at last we design the solutions of the system and build the system's framework, finally p
