The Research Of Shipbuilding Universal Process Modeling Based On XTCAPP

As the continuous development of the 21st century economy, the demand of transport equipment is increasing, It is particularly remarkable that the requirements for ships. Because of the strong transport capacity of ship and its cheapness, the status of ship transport is increasing quickly. So shipbuilding is also important.Shipbuilding industry is very special; the main characteristic is that the very large number of parts and the very complicated process. The level of shipbuilding has a direct relationship with technology, also is the management level and digital level. At the same time, the transition of shipbuilding has been prevailed for a long time, and the shipbuilding pattern based on information technology is gradually developing. As the use of CIMS, parallel engineering, agile manufacture in ship industry, the need of CAPP is becoming much more urgent for shipbuilding enterprises.Under such circumstances, the modeling technology of the ship universal process is studied on this article. As XTCAPP to the platform, equipment database and process information database are established, and process card templates are designed, which is Suitable for shipbuilding. A lot of time can be saved, and the efficiency is improved, CAD files are used, so the product information is shared.In this article, as the lean shipbuilding to guide, the main work is:First, Learn the background of current shipbuilding, and the trend of digital shipbuilding. The composition of the ship construction process are summarized and reviewed, which is ready for the use of XTCAPP in shipbuilding. Second, The CAPP thought and the characteristics of t ship manufacturing process are researched and analyzed, and process card templates for shipbuilding is designed. Ship manufacturing process. Database model is created, which is based on database design theory. At last, the experiment is done on the platform of XTCAPP.
