摘要

由於在電腦輔助同步式淨形產品設計與製程開發環境中,各活動間模式轉
換困難與不一致性,以及特徵萃取技術之的困難,影響了各開發活動之間
的配合和資訊傳遞,使得產品開發效率與成果不彰,這種情形凸顯進一步
整合同步式產品與製程開發的各項主要開發活動,使得整個同步式開發環
境更加具有效率和系統化,有其相當的必要。本研究的主要目的將在此同
步式開發模式中,利用以特徵為基之模式化方法,發展以特徵為基之產品
模型及模具模型之轉換方法,除了提供模具製程規劃系統利用經由轉換得
到之特徵,進行製程規劃,毋需從事高難度之特徵萃取的工作外,產品設
計活動可根據轉換之模具特徵,在產品設計初期即考慮其所設計特徵之優
劣。在此同步式開發模式下,經由各活動間模型的轉換與維護,使產品設
計、模具設計、製程規劃三者間得以同步及整合,除了實現電腦輔助同步
工程的理想,並進而提昇產品設計與製程開發之效率,提高產品的品質,
並降低成本,以期達到提高產品競爭力的目標

Abstract

Model transformation and refinement in between productand
process activities is the corner stone of computer-
aidedconcurrent product and process development. Conventionally,
feature recognition and extraction techniques were used
indeveloping feature-based model for process planning.
Howeverdue to the limitation and difficulty in feature
recognition,the goal for integrated product and process
development is not yet achieved. This thesis develops a
feature-based model refinementmethodology, including a model
refinement procedure and mechanisms,that is able to transform
feature-based molding product modelsinto feature-based mold
models to support computer-aided concurrentmolding product and
(1) the feature recognition difficulty iseliminated and thus
increases the efficiency of model refinement ,(2) the
consistency between product models and mold models can
bedynamically maintained that makes integrated product and
processdevelopment possible and (3) it supports various molding
productand process development activities such as cost
effectivenessevaluation, mold manufacturability assessment and
mold manufacturingprocess planning. The result of this research
enables computer-aidedconcurrent product and process development
and thus help increasesproduct quality and reduces product cost
and development time andeventually increases product
marketability.
