摘要
台灣工業型態自早期的OEM已慢慢的蛻變成ODM，更逐漸變為OBM；在這產品生命週期日趨短暫且製造成本高漲利潤微薄的今日，必須加速上市時間、降低和控制成本、增強產品靈活性並提高品質及不斷創新。
在這科技日益精進的今日，積極推動電腦輔助研發工程的技術，結合電腦軟體技術於產品設計、分析與製程的趨勢，將產品走向高品質、低成本與短開發時間構面要求。
所謂：「機械為工業之母，模具為機械工業之基礎」。本研究以沖壓板金開發為對象，整合逆向工程(RE)、電腦輔助設計(CAD)、電腦輔助工程(CAE)、電腦輔助製造(CAM)等電腦輔助研發(Computer-Aided Research and Development；CARD)技術。先利用RE逆向工程設備擷取產品點資料，準確的進行實體及曲面之建構；以CAD提供各種產品數位圖面及設計技術，CAE快速分析及測試來確保設計之產品品質，CAM預覽與確認生產製程及加工的有效控制。CARD已蔚為設計工具主流，實體設計的方法和分析，減少設計階段錯誤所造成不良製造流程，增加設計上的品質。本研究論文以大卡車前保險桿開發為實例驗證對象。

Abstract
Taiwan industry has been evolved gradually from early OEM style to ODM, and even to ODM. With the facts that the product life cycle is getting shorter and shorter, the manufacturing cost is getting higher and higher, and the profit is getting thinner and thinner, industry needs to speed up time to market, reduce and control cost, increase product flexibility, improve quality and innovate continuously in order to survive.
Due to fast technology evolution, product quality, development time and cost can all be improved by proactively introducing computer-aided research and development (CARD) tools into the product development process and applying the CARD technologies on product design, analysis and manufacturing.
With the words that: machine is the mother of industry, and mold is the foundation of machine industry, the purpose of this research is to study the development process of sheet metal stamping by integrating CARD technologies including reverse engineering (RE), computer-aided design (CAD), computer-aided engineering, (CAE), and computer-aided manufacturing (CAM).
The process uses RE to acquire point data and construct accurate solid and surface models for the target product. Then, uses CAD to provide digital drafting and designing techniques, uses CAE to analyze and examine the design quality, and finally uses CAM to review and make sure that the manufacturing process is under precision and cost control.
This research has proven that CARD is the main stream of product development. It can be used to increase the efficiency of product design and analysis, reduce possibilities of poor manufacturing caused by any design issues, and improve product quality and time to market. This research uses the development of truck bumper as a case study for the proposed process.
