  • 渦輪葉片為航太、汽車與冷凍空調業的關鍵性零組件,其設計與製造能力代表整體的工業技術水準,先進國家在此一領域上均投入大量研究資源。渦輪葉片的開發屬於高度分工的產業,其外型設計涉及尖端的流體力學分析,而葉片製造則由專業的加工廠擔任,需要專精的三維幾何模擬與切削技術。由於幾何形狀複雜,五軸切削是比較適合的葉片製造方式,其中最困難的工作為刀具運動的路徑規劃。雖已有文獻探討基本型式之渦輪相關製程以及各項議題,但是對於含分離葉片離心式渦輪之整合性加工規劃技術尚無人討論。本研究將針對含分離葉片之離心式渦輪發展五軸加工規劃法則,主要貢獻在於「側銑加工刀具路徑線性插補法則」、「平滑化刀具軸向演算法架構」以及「含分離葉片離心式渦輪之五軸路徑規劃架構」三項,最後並實際利用五軸工具機切削驗證結果。文中提供一套有效的規劃法則,幫助含分離葉片之離心式渦輪進行製程規劃,期能提高加工效率以及切削精度。
