摘要

High-level process planning plays an important role in determining candidate process domains at the configuration design stage. Determining the most appropriate manufacturing process at the beginning stage of the design process becomes critical, since changing the processes domains later increases the product development cycle and the product development cost. However, high-level process planning systems traditionally lack a sense of an integrated design synthesis and design evaluation.; The main objective of this research has been to develop a FEature-Based Design And Process Planning (FEBDAPP) system that helps designers decide whether or not the design is worth pursuing by providing manufacturing advice to designers during the design process. In order to achieve the main objective, the following steps have been accomplished: (1) developed a hybrid system incorporating design by feature and feature recognition approaches capable of reducing the complexity of feature recognition algorithms without sacrificing flexibility in creating a part design and, (2) developed a comprehensive set of feature mapping algorithms capable of transforming the primary part representation into the secondary part representation so-called application-based features that are required as inputs to downstream applications, and (3) developed a CAD-based interface capable of integrating a current CAD system and a high-level process planning system.; This research contributes significantly to the availability of early design tools that enhance and at the same time shorten the design process cycle. The implementation of feature technology in this research will support the development of applications such as tooling cost estimation and manufacturability analysis. Finally, the FEBDAPP system is intended to be an effective concurrent engineering tool that bridges the gap between design and manufacturing.
