Database construction and data retrieval for optimal casting design

摘要

The existing optimal casting design data retrieval system enables a user to easily retrieve only the needed text data from a huge text database. While the necessary data can be found quickly through search terms, however, it is difficult to access know how gained in the field and the shape data on casting design models. To solve this problem, an optimal system has been developed to retrieve all the shape data generated in the field. The features and keywords of comparative optimal casting designs are extracted and stored in the shape feature keyword database. Through the user interface, the two-dimensional and three-dimensional shape data and shape keywords of a product model are compared with those of casting designs stored in the database. In this way, the optimal casting design most similar to a good model is chosen.
