The Construction of Expert System for Press Die Layout Design

[[abstract]]沖壓鈑金主要是利用沖壓設備及模具，將金屬鈑金加工快速獲得所需成品，由於沖壓生產有快速、方便、生產成本低…等特性，所以鈑金沖壓技術廣泛的應用在汽車、航太產業、家電用品產業及3C…等產業。鈑金的開發相當冗長及不確定，如在最終階段發現設計偏差導致產品不良，只能反覆進行設計變更、機械加工、合模、試模，直到成品符合所求為止。為因應『產品快速投入市場(Faster Time to Market)』及『第一次就把工作做對』的需求，整合各階段開發成功及專家的經驗實在有其必要性。 為有效的縮短產品開發時間，配合同步工程(Concurrent Engineering)及建立協同工作環境(Collaborative Workspace)，以達到產品快速投入市場的需求。如何有效的利用電腦…等的各式工具，並迅速結合既有的產品開發成功及專家的經驗，適時提供正確、有效的建議，避免、減少不良問題及錯誤的發生，有效縮短產品開發時間，提高新產品開發成功及日程掌控的能力，加速產品上市的速度成為鈑金沖壓製造業者求生存、求發展的重要議題。 本研究主要目的在於設計開發出一套沖壓鈑金模具工法設計專家系統及相關的解決方案，其目標在於規劃、分析、建構沖壓鈑金模具工法設計知識庫的架構，期望能有效的結合並充分利用以往開發成功及專家…等寶貴經驗，能適時提供正確、有效的建議，強化沖壓鈑金製造業的競爭能力。[[abstract]]Press product mainly use press equipment and die to process metal sheet and gain the product we need. Because it has the characteristic of fast、convenience and cheap, press produce have been used in auto、aircraft and electric industry. The development of press product is long and un-certain, when you mistake you need pay much time to revise. For the requirement of faster time to market and right to do first time, it is necessary to integrate successful development and expert experience. For the requirement of faster time to market, shorten the time of development and construct the environment of concurrent engineering and collaborative workspace is very important. How to use computer to integrate successful development and expert experience and provide timely right and suggestion, avoid the occurrence of mistake is very important issue to press manufacture industry. The purpose in this paper is building and developing the expert system of press die layout design and relative method of solution. The goal is plan、analysis、construct the frame of knowledge base for press die layout design, expect effective integrating and full use the precious experience of successful development and expert, can provide timely right and effective suggestion, strengthen the competition capability of press manufacture industry
