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.
