中文摘要 | 金屬粉末冶金與陶瓷粉末成型產品是各種高科技產業之重要關鍵零組件,應用粉末冶金與粉末成型技術製造之高科技產品,例如:自潤軸承、碳化鎢切削刀具、摩擦零件、電子封裝零件、感測器……等等。 粉末冶金之製程包括:產品設計、模具設計與製造,粉體混合、粉末加壓成形、生胚燒結、後處理加工;由於粉末必需在模具內經加壓後才能得到產品之基本形狀,因此,粉末冶金模具是粉末冶金製程中極為重要之機構,傳統上以手工平面繪圖設計模具,電腦軟硬體發達後改由電腦輔助平面繪圖取代,由於2D繪圖軟體,遇到複雜之曲面零件時,無法確保產品或模具零件各幾何尺寸間之完整性與正確性,另一方面,2D繪圖無法快速支援設計變更之需求,因此目前皆仰賴經驗豐富之工程師進行此項工作,造成人力與時間之耗費。另外,模具加工必須仰賴經驗豐富之製造工程師進行撰寫,若遇到人員流動,或因工程師編寫程式之技術不足,都極易造成製程之停頓。 目前粉末冶金產品之專業研發與生產公司,因為技術層面缺乏,新產品開發所耗費的時間甚長,而且產品僅局限在普通之金屬粉末冶金製品,國際競爭力無法提昇,本研究針對新產品研發階段所面臨的技術瓶頸提出解決方案,開發新型高附加價值之粉末冶金產品(例如:陶瓷粉末成型製品),以達到技術提昇之目標。 本研究首先整合參數式電腦輔助設計及電腦輔助製造系統,應用參數式CAD系統將粉末冶金產品設計概念具體呈現後隨即開發其模具,然後以CAM系統製造粉末冶金模具,透過產學合作,在專業粉末冶金廠進行模具測試以及粉末成型、燒結等後續製程,製造出實際之粉末冶金產品;整體研究將可提昇粉末冶金產品設計/製造自動化的能力,縮短研發週期、加速市場反應能力及節省人力成本。 |
英文摘要 | Metal and ceramic powder processed products are key components for various high-tech industries. These high-tech products manufactured by powder metallurgy and powder formation technology are exemplified by self-lubricating bearings, carbide cutting tools, friction parts, electronic packaging parts, and sensors. Powder metallurgy processes consist of the following procedures: product design, mold design and manufacturing, mixing of powders press formation, sintering, and post-process treatment. Since the powder must be pressed in the mold to obtain the basic forms of the designed product, these molds are extremely important components for powder metallurgy processes. Traditionally, molds were manually designed. Later, with the development of computer software and hardware, a computer-aided 2-D drawing was used. However, these 2-D technologies can not guarantee the integrity and correctness of geometric dimensions of products or mold parts, especially if the parts have complicated surfaces. Also, such a 2-D design is not capable of supporting rapid changes in design concepts. That is why current mold manufacturing relies on experienced engineers, resulting in waste of time and manpower. Besides, mold machining must depend on experienced manufacturing engineers. In cases of personnel change, or insufficient experience or ability on the part of the engineers, the manufacturing process can be easily halted. Presently, in companies that research and develop powder metallurgy products, new product development takes a long time due to such technical difficulties. In addition, these products are limited to ordinary metal powder parts, lacking competitiveness in the international market. The objectives of this research are to propose a solution to the technical bottleneck in the new product development stage, to develop products with high added value (e.g., ceramic powder processing), and to promote relevant technologies. This research will initially integrate parametric computer-aided design and computer-aided manufacturing systems, suing a parametric CAD system to express design concepts into solid models, then developing press molds, followed by manufacturing of the molds using a CAM system. Testing of molds, powder formation, sintering and post-sintering procedures will be conducted in professional powder metallurgy factories through cooperation with industry, to produce final powder metallurgy products. This research will be able to promote automation of product design and manufacturing, shorten development time, increase ability to react to a changing market, and save cost and manpower. |
