摘要
模具設計的良否對淨形產品之開發流程中具有相當重要的影響。傳統
之模具設計由於經驗工程師養成不易，且在設計時與產品設計、製程設計
及製程規劃間，無法有效的溝通協調所造成的錯誤，使模具設計成為耗費
人力、物力、時間及資源的生產瓶頸。近年來，透過同步工程的概念，可
在設計初期考慮並解決產品開發流程中的相關問題，以提高產品及製程發
展的品質與效率，因此透過此一概念來幫助模具設計、解決傳統缺失，為
研究上的一個關鍵技術。 本研究主要目的在建立一系統化同步式之模
具開發模式，並依此提出一個能將產品設計、製程設計及模具製程規劃等
程序加以考慮之同步式電腦輔助模具設計系統架構。並在此一架構下從事
相關知識庫系統之研發，以幫助模具開發之合理化、系統化與同步化，並
加速達成自動化之目標，進而提昇模具設計之效率與品質、降低成本。
透過IDEF技術，本研究以結構化系統分析方法，針對模具開發程序研究各
設計階段的工作特性與相關性，再以同步工程之概念及系統工程技術建立
一系統化、同步式開發模式，進而建立一同步式電腦輔助模具設計系統架
構。根據產品生命週期之整體考慮，本研究針對模具設計需求依資料工程
的技術建立設計過程中所需的資料庫，並由物件導向技術及知識工程方法
考量產品開發流程發展一協同式模具設計知識庫，進而增加模具設計之完
整性。
Abstract
Mold design plays one of the key roles in net shape product
and process development. Conventionally, it performed by
experienced designer without sufficient communication with
product designers, mold manufacturing process planners and mold
fabrication engineers. This leads to the high cost, long
development time and inconsistent quality of mold design. In
resent years, the concept of concurrent engineering has been
widely employed to improve product and process development
efficiency and quality by resolving all product life cycle issue
at the early design stage. However, how concurrent engineering
can help in mold development is still a research issue. The
objective of this research is to facilitate the rationalization,
concurrentization and automation of mold development process and
thus improve the efficiency and quality, and reduce the cost of
mold development by: (1) developing a systematic and concurrent
mold development model, (2) developing a computer-based mold
design framework based on the model, that concurrently takes
issues of product design, process design and mold fabrication
into consideration, and (3) developing knowledge bases to assist
concurrent type of mold design. IDEF structural analysis
methodology was employed to investigate the characteristics of
mold development process. The concepts of concurrent engineering
and the technology of system engineering were used to develop
the computer-based concurrent mold design framework. In
consideration of other molding product and process development
activities, databases and knowledge bases for mold design were
developed using technologies of data engineering, knowledge
engineering, and object-oriented modeling.
