由於傳統的玻璃瓶設計程序過度依賴設計人員的經驗和模具工的技術,需耗費大量的時間與精力在計算與繪圖,工作負荷量大且出錯機率高,間接影響了產品的設計速度與工作效率。因此,如何提高玻璃瓶製品的設計智能化將是玻璃瓶設計CAD領域研究的重點。本研究將知識工程(Knowledge Based Engineering,KBE)技術導入玻璃瓶設計程序過程,並利用UG軟體的二次開發工具UG/KF語言,開發以產品知識庫為中心的玻璃瓶專業化CAD建模系統,從而實現設計知識的重用,輔助設計人員進行產品的快速設計,幫助企業縮短產品開發週期,提高技術創新能力。 最後,透過以玻璃瓶的知識建模與最佳化設計來驗證本研究所提出的設計思維與設計方法,期望能快速有效的設計出所需的玻璃瓶外形及其與製程相關模具,以便快速反應市場的需求,提升企業競爭力。
The process of traditional glass bottle design is highly-dependent on the experience of the designers and the technique of mould workers, which is time-consuming and labor-intensive in the calculations and drawing. It is heavy-loading work and has a high error frequency, which indirectly slows down design and decreases work efficiency. Therefore, the intellectualized improvement of glass bottle design is an important subject in the CAD design. In this study, Knowledge Based Engineering (KBE) is introduced into glass bottle design, utilizing the UG/KF language of a secondary development tool from Unigraphics (UG) software to develop a professional CAD mould-building system with a Product Knowledge Database as the core. This system will be able to realize a novel way of designing with a knowledge base, accelerating the work of designers; it will further shorten the product development cycles for enterprises and improve their high-technology innovation abilities. In summary, by establishing knowledge base mould construction with optimal design, this study proposes an ideal method for glass bottle design, hoping to cut down the time required for contour design and the manufacture process of the glass bottles. This will increase the response time to market demand and improve the competitive ability of enterprises.
