摘要

在金屬鑄造製程中，鑄件成型時的凝固熱點通常會形成縮孔缺陷，因此在進行鑄造方案設計時，需判斷凝固熱點位置，並在此位置設計冒口（feeder），以消除縮孔的發生。一般而言，運用鑄造成型模擬軟體，可判讀出鑄件成型的縮孔位置，但模擬軟體價格昂貴，且模擬完成的時間常在數小時以上。本文“自動生成最佳冒口的系統”可幫助鑄造界真正解決複雜鑄件形狀的冒口設計，是屬於專門的電腦輔助應用於鑄造冒口方案設計（Computer-Aid for Feeder Design）的重要軟體。可以讓設計者在第一時間，由軟體計算便可以得到正確的最佳化冒口設計，不需要再使用試誤法。因此，本文所構想的新一代系統，可以提升鑄造界轉型、讓鑄造界可以縮短開發時間，以及節省不必要的成本浪費。

IIn the metal casting process, the solidification hot spots developed during casting molding usually form shrinkage defects. Therefore, when designing the casting runner system, it is necessary to determine the location of the hot spots during casting solidification and design a feeder at this position to eliminate the occurrence of shrinkage. Generally speaking, the casting molding simulation software can be used to determine the position of the shrinkage cavities of the casting, but the simulation software is expensive. Furthermore, the simulation takes a very long time. This paper introduces computer-aided software to optimize the feeder design for castings with complex geometry. It helps designers to get the correct and optimized feeder design through short-time simulation based on the algorithm embedded in developed software, without going through the trial and error process.
