Research On Tool Management System Of Information Manufacture

Tool management is one of the most important parts in information manufacture, especially to mechanical manufacture workshop. The rationality and scientificity of tool management are crucial to the dependability of the manufacture system and the efficiency of the production. Furthermore, the constitution of the tool management system give the tool information to the topper management system and CAD/CAM/CAPP system of information manufacture system, and make the information streaming effectively of the whole manufacture system.In this article the tool management system was throughout studied, especially for several key technologies, which are tool dispatching technique, tool monitor technique, tool database structure and so on. The following are the main achievements in this article: Through the introduction of the representative configuration of tool management system, the component of system and the function of each part were throughout studied. In this part we put an emphasis on analysis the move and operate process and the major function realization of each part in tool management system It is first time to use the agent in tool dispatching problem. In this paper Multi-agent tool dispatching model was constructed through analyzing the specialties of tool dispatching, and agent dispatching repository was made up through analyzing strategies of tool dispatching, which include tools contest strategy and tools distribute strategy. Multi-agent tools dispatching system, which has the such aspects as dynamic dispatching, cooperate solution and distribute dispose, can complete the tool dispatching tasks in manufacture system successfully. Tool monitor based on Back Propagation neural network are researched. Through analyses of tool monitor development tendency on software, hardware and theories, based on the tool monitor study level and application in the world, tool monitor system was constructed. The tool monitor theory and construction of tool monitor system was mainly analyzed. To identify tool cutting state by using vibration signal and AE signal. The disposed signals are sent to BP neural network, so the tool cutting state can be recognized. Based on the tool cutting state can realize the control of tool and machine tool. Tool information database was constructed. It was introduced the design progress of tool database in server part. First, analyze tool information needs, construct tool information model, then design database concept structure and logic structure, at last constitute tool database by Access. Tool management system software, which was based on the network database, and has Client/Server structure, was programmed by Visual Basic, and was debugged and run very well. It can communicate successfully with tool database, can satisfy the need of tool managementsystem, and can realize tools control. This program has Ergonomics graphical interfaces and perfect online help, accord with human being management style, also has good maintenance and extension.At last summarized the study work and achievements of this article, and made suggestions and tentative plan about the next steps of this study.
