AN APPLICATION OF ASSEMBLY STRUCTURE IN WELDING ESTIMATE OF WELDING OBJECT IN MANUFACTURING DESIGN

摘要

Welding vessel objects such as heat-exchanger, oil-tank and other civil-used pressure vessels are comparatively large size products. Design works for such products not only concern with the geometric data, more important aspect is to treat with the design knowledge used in design process. But traditional CAD systems generally depend on shape-oriented approaches and pay less attention on the features of design and dealing with design knowledge. Therefore, there has been a considerable growth of interest toward knowledge-based design support systems. We have proposed a design object model for manufacturing design of welding vessels. In this model, the assembly structure of a design object is represented by the essential design elements and their dependencies. This paper discusses its application and focus on welding estimate of a welding object and dealing with design knowledge related.
