Research And Application Of Template Mechanism In The Management Of Product Process Information

With the gradual development of enterprise's information construction, the demand for CAPP system of enterprises, no longer confine to its solving the problem that technologist fill in the craft card, it considers to be mostly creation, flow, effective management and maintenance of process information in the whole process of product manufacturing. Through the construction of template mechanism, CAPP can easily input and output of product process information, realize the standardization of product process information management, at the same time, can integrate the information with other system. So this thesis first discuss the implementation of template mechanism in product process information, then provide CAPP with intelligent tool which can be expanded in future based on the template mechanism. Then, some key problems should be discussed in the thesis.For establishing the mapping relation between process information objects and process card contents, it is necessary to establish the template mapping mechanism of Process information. Through analyzing process information and the inside association among process information, study on the composing content and actual conforming method. The template mechanism is useful to organize and manage process information, and integrate with other system;Study on the batch input of product process information based on template mechanism. For utilizing the existent process information in the development of enterprise, study on the batch input of product process information based on template mechanism, CAPP can construct standardized, unified and integrated process information, and construct configuration tree of process files. By this means, hierarchy of product process information is very clear, and it is helpful to organize product process information and manage process files;Study on context awareness based on process template. Aiming at a great deal of interactive between human and computer in CAPP system, it is proposed that context awareness based on process template. That is to say, by using template mechanism, according to temporal context, CAPP searches the correspondent process knowledge from process knowledge database. By this means it can enforce the intelligent assistant function when technologist set down process information.On the basis of above theoretical achievement, linking with several enterprise instances, aiming at problems put forward by enterprise, by utilize the second development interface of InteCAPP system, realize custom development for enterprise, enforce the context awareness function based on template mechanism.
