模具設計與CAD的知識整合架構與管理

大型的消費性電子產品隨著大眾消費型態的改變成為市場主流，生產產品的大型模具也因此孕育而生，為配合產品生命週期的縮短，模具開發時程成為重點項目，模具設計引導流程，能改善設計者間的認知差距，讓模具設計能更流暢的進行，而大型塑膠模具與過往的中小型模具又有著不同的設計重點，藉由標準化流程將相關的設計知識內化，達到知識管理之目的。本文利用電腦輔助設計軟體與網路技術整合，建立大型液晶顯示器螢幕框架之模具設計引導流程，藉由過往的設計經驗，重新修正設計步驟，對系統提出相關的改善，增加設計者對於系統使用的變化與彈性，使得設計流程能更簡化。在拔模功能中，彙整了拔模設計的基本功能外，本文利用物件著色的直覺判斷方式，輔助拔模角設計步驟，改善過往使用截圖或文字紀錄等方式進行設計前後比對的困擾，讓工程師能更快速且明確的辨識差異；利用知識工程的核心概念，將參數功能與設計手法及設計工具做結合，運用到協同設計上配合資料庫整合，達到設計模型的管理，同時帶入相關設計資訊達到知識整合之目的，協助工程師設計相關模型，縮短產品開發時間，並減少人為的設計錯誤。

With the change of mass consumption patterns large consumer electronics products become mainstream, therefore large-scale production of the product mold born out. For shortening product life cycle, mold design become the most important procedure of the project development process. the collaborative navigation system for concurrent mold design can improve cognitive gap in different designer and let mold design can be carried out more smoothly. However the large plastic mold has a different design focus between small and medium size plastic mold, with standardized process to internalize the relevant design knowledge and to attain the purpose of knowledge management. This study integrate the CAD software and network technology to establish a navigation system framework for large LCD display screen mold design. Use previous experience and redesign steps amended to improve the system more variable and flexibility, making the design process more streamlined. In the draft functions, synthesize the whole of the basic functions of the draft design and use objects colored auxiliary draft angle design let engineers can more quickly and clearly identify the differences. Using the core concepts of knowledge engineering, the parameter function combine the design methods and tools. Applied to collaborative design with database integration, to manage the design model, while into the relevant design information to achieve the purpose of knowledge integration, help engineer’s design-related model, shorten product development time and reduce human design errors.
