AN EXPERT SYSTEM APPLICATION OF THE INITIAL ESTIMATE ON INJECTION MOULD MANUFACTURING

摘要

The innitial estimate calculating work of the mould is achieved by experienced and skilled engineers. However, at most mould manufacturing enterprises, there are frequent cases that they calculate by rule of thumb because they neither have established standardization nor determined clear estimate method. As the result, in fact, it is natural that not only much time is wasted but absolutely draw up and submit non-consistent quotation, which leads to raise major and minor quarrels with their clients continuously. Therefore, in order to remove such a problem point, in this study, the development and application of an expert system is studied for estimate calculation at the injection mould manufacturing process. The application of the developed system to the working site has the advantage that even beginners can create better quoting result than experts can. The developed system used visual BASIC language and SQL database under Windows and Windows NT environment.
