摘要

經驗傳承一直是模具設計的最大問題，主要的原因在於設計流程並未標準化與系統化，因此模具設計能力常掌握在具有經驗的專家身上，有鑑於此，因此本研究的目的在於開發一套汽車鈑金模具的設計系統，主要是透過專家訪談的方式來收集模具設計的知識與規範，並以工作分析的概念將模具設計的流程細分，細分後之設計流程再依重要性與順序性訂立一個標準作業流程，希望藉由標準作業流程(standard operation procedure, SOP)可以將模具設計的概念以系統化呈現方式傳達給設計人員。

本系統建構於CATIA平台上，主要是藉由CATIA所提供之二次開發的功能建構汽車鈑金模具之設計工具，並以VB程式語言建構使用者介面，使用者只需依程式指示依序執行，即可在CATIA上完成鈑金模具之設計，且因系統結合參數化設計的概念，因此可以保有設計彈性，可以適用於不同廠商的設計規範，另外，系統化的呈現方式除了可以加速設計人員掌握模具設計的要領之外，還可以增加設計人員除錯的能力，設計人員還可以藉由系統所開發之輔助工具來縮短設計時程。

Experience inheritance has been the major problem in the mould design. The main reason is that the design flow is not standardized and systematized, so the capability of mould design is mastered by some experts with rich experiences. Therefore, this paper proposes to develop a design guided system for mould design of automobile sheet metal. It collected knowledge and operation process of mould design through the interview of experts, and subdivided the mould design processes based on the concept of job analysis into some segments of process. After subdivision the design flow, some standard operation procedures can be established in terms of the importance and sequence order. Therefore the concept of mould design could be more clearly delivered to the designer in the systematic manners by means of standard operation procedures.

The system is based on CATIA platform, which builds the design devices of mould mainly through the functionality of secondary development of CATIA system. In addition, with the assistance of VB programming for constructing the user's interface, the user only fill the necessary information based on the program instructions, and then complete the whole design drawing of sheet metal. The system combines the concept of parameterized design, so the system also maintains design flexibility and capability to fit the different manufacture factories. Furthermore, the systematic visualization mode could not only assist the designer for fulfilling the key issues of mould design, but also improve the designer capability for detecting the design errors. The design time can be greatly decreased through some auxiliary tools developed by the system.
