Research Abstract |
The control of precision has been an important part of the manufacturing process of welded structures. However, conventional methods were largely dependent on experience and they did not have clear theoretical bases. Also, the analysis of the error observed in the process is limited within each process. The problem of precision is not analyzed as an overall problem which involves many processes and their interfaces. Thus, the manufacturing process is divided into cutting, bending and welding and theories and finite elemnt codes to analyzed the individual process are developed in the first year of the research project. Then, fundamental guideline to combine these for making a system to control the precision is studied from the point of view of the total manufacturing process in the second year. Generally, manufacturing cites, such as building dock, and computer simulations are entirely different in nature and it is very difficult to make mutual understanding between people working in these sections. To introduce computer simulation, good interface is necessary between menufacturing and Computers. In this research, strategic and conceptual modellings are proposed as such interfaces. Their effectiveness is demonstrated using various examples of applications.
