CAD/CAPP Research and Practice of Special Welding Shell Parts

摘要

This paper adopts the parameterized designing method of feature assembled and feature unit. For the feature of non-conventional parts, such as welding box and bearer, using the Visual C++ and AutoCAD as soft tools, the system successfully carries out the basic function of feature assembling, the processing of two-dimensional figure, the building of three-dimensional feature, the automatic producing of technical papers, and so on. The integration idea and design methods of this system can be served as the preference to CAD/CAPP integration for other non-conventional parts.
