| Summary: | 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.
