臺灣博碩士論文加值系統

以往沖壓模具設計工程師進行產品設計時，常先以人工繪製草圖或製作原型來表達自己的設計理念，目前大部分的企業都使用過2D系統，並以解決部分實務問題，未來CAD發展將以3D實體模型為主流，以提高模具精度及降低產品設計變更的機率，未來更可以結合製造與工程分析，以達到整合性應用發展。
本研究利用CAD軟體 Pro/ENGINEER視窗下的瀏覽器，開發出具知識管理之網路化精密沖壓概念設計與模具設計。概念設計屬於模具開發的初期階段，針對零件做模具設計的前置作業，並運用資訊技術將沖壓設計流程加以彙整組織，而形成使用者方便使用的智慧型管理系統，配合以網路化與客製化的引導系統對產品特徵做分類與分析，建立出產品特徵的知識管理，進而達到特徵導向沖壓零件概念設計。概念設計模組主要針對客戶的產品提案進行可行性的評估、模具設計與製造前的初步分析流程，概念設計模組包含一切標準化的設計步驟與常用的設計工具。經由此系統的開發與沖壓模具廠實務的結合，能夠大幅降低沖壓模具生產週期與加強工廠管理的便利性，以提升沖壓模具產業在全球的競爭力。本論文研究則在於開發一套以CAD軟體為基礎之網路化與客製化之精密金屬沖壓模具概念設計引導系統，結合專案的執行管控來達到產品設計引導之目的，進而達到縮短產品開發週期與無紙化的趨勢。模具設計模組，將拆模過程工作模組化，並且與概念設計作整合運用，包含拆模過程標準化和自動化，與常用的設計工具和系統化的引導；3D的圖面完整、清晰易讀且修改方便，可以加速設計者對產品的了解，並建立拆模歷史資料庫提供新進員工學習，在引導過程中，零件設計標準化，減少因個人因素而產生不必要的設計差異性，且模型利用參數化設計，可以縮短拆模的時間。

Metal stamping components are the basic elements of the electronics industry, due to the rather widespread application of products, the main future of the industry continues to grow and precise in domestic downstream industries, especially due to the rapid development of 3C products and the high development rate of information hardware industry and communication industry, under the integrity of the industry upstream and downstream.
Nevertheless, the majority of domestic stamping industry belongs to medium and small enterprises; therefore the research capacity is limited. In this case, the force of government resources and research institutes needs to be combined. Currently, the research of stamping techniques in countries around the world mainly directs at precision, automatization, energy resource conserving, and high value. We should master the development of the domestic electronics industry and the complete advantages supplied by the industry; on the other hand, in the stamping technique aspect, we should direct at accomplishing the goal of mini-precise shaping and automatization in order to increase technique level and raise product additional value. Moreover, increasing mold life-span to lower cost and raise industry competitive strength is one of the main efforts.
The main goal of this project is to establish a set of CAD/CAM centered 3D precise stamping mold collaborative evaluation and digital integration system of design and manufacturing, and to modulize stamping mold industry tasks. By manufacturing evaluation, modules transparent the price of molds and is able to quickly set a reasonable quotation. Collaborative 3D mold design module immensely shortens product development life cycles; production manufacture modules optimize manufacturing scheduling to speed up the manufacturing after. Each module is able to operate independently or apply in integration and to apply knowledge management on mold knowledge experiences, not only does this allow the design process to be even more complete and perfect, it also assists in speeding up the training of personnel, decreasing the effect of stamping mold personnel leaves on enterprises. Through the practice integration of the development and stamping mold factory of this system, the stamping mold production life cycle is immensely decreased and the conveniency of factory management is strengthened, increasing the global competitiveness of domestic stamping mold industries.
