碩士 === 國立成功大學 === 製造工程研究所 === 85 === Copyright (c) 1990, Microsoft Corp In the life cycle of product and process development, process planning is the critical activity for reaching the goal of low cost, high quality and less developing time. The computer-aided process planning(CAPP) is used to facilitate this activity in a concurrent product and process development environment. The domain knowledge play an important role in this development cycle to support the process planning for producing a good process plan, then a good product could possibly be made. Unfortunately, the domain knowledge is hard to accumulate and most of it is diversified to the individual expert. Rework and redesign occur frequently in the product development cycle due to the lack of manufacturing knowledge on the part of product designer and mold designer, causing higher cost, delayed schedule and lower quality.This thesis presents a systematic approach to develop a knowledge server for computer-aided concurrent product and process development especially for the injection molding product. Knowledge from each level of knowledge is abstracted using a systematic method. A featured- and knowledge-based computer- aided mold manufacturing process planning is developed and supports this knowledge server and based on this CAPP module, a CAPP advisor is also developed to support the mold''s manufacturability evaluation during product design and mold design stage, thus expedites the product development cycle. The cost reduction, high quality part and shorter developing time are easily achieved.
