摘要

近年來為了因應全球化生產，產品開發週期縮短，業者須具備快速反應能力以獲得國際訂單，快速試作技術因此興起。透過數位路徑控制以及減少專用模具使用且可於短時間內生產部件的漸進成形技術為目前國際於相關成形技術的發展趨勢。本文以一深引伸零件作為漸進成形試驗載具，首先透過成形路徑設計及製程參數建立CAE分析模型，並進行成形道次規劃。而後於金屬中心建置之漸進成形試作場域以機械手臂進行實際試作驗證，並將CAE分析結果於成形之鈑件進行比對，結果顯示透過漸進成形CAE分析進行路徑及成形道次規劃可提升成形後鈑件品質。

In recent year, to adapt to globalization for shortened lead time and expedited reaction to product development, the manufacturers have to adjust themselves to develop rapid prototyping techniques in order to attract international demand. Incremental forming technology, which manufactures products in a short time with digital path control and reduced number of forming tools, has become the current development trend in global prototyping technology. A deep drawing part is formed by incremental forming process in this article. The forming steps is first designed through the CAE model established through forming tools path design and process parameters. Then, the incremental forming process is carried out with robot in the forming lab built up by MIRDC. And the formed parts are compared with the CAE analysis. It shows that the formed parts quality of incremental forming can be improved through the path and forming steps designed with CAE analysis.
