本論文提出針對五軸CNC工具機中轉動軸之動態與靜態誤差量測方法，針對動態誤差，使用量具為雙球桿量測儀，搭配線性軸轉動軸與雙轉動軸同動循圓量測方法，成功量得五軸CNC工具機中轉動軸之動態誤差。所提出之方法保證循圓量測過程中，轉動軸反向時，線性軸之軸向量測靈敏度為零，若只考慮線性軸之線性軸向誤差，則轉動軸反向時所量得之誤差全由轉動軸貢獻。
本方法具有一般性，任何構型之五軸CNC工具機皆可使用本方法之推導邏輯得出適合之線性軸轉動軸或雙轉動軸同動循圓路徑，本方法計算出之測試路徑可使用多線段(G01)之NC檔案輸入CNC控制器中進行量測，可應用於任何具有路徑預視功能之CNC控制器上。另外，本方法所量得之純動態誤差是由總成量測誤差減去定位量測誤差所得，可迴避安裝量具時之安裝誤差。模擬與實驗結果證明本方法可量出五軸CNC工具機中轉動軸之動態誤差。
運用本論文提出之線性軸轉動軸同動循圓量測方法，可檢測轉動軸全行程之反向誤差，透過多次量測與適當之循圓路徑安排，可檢測出五軸CNC工具機中轉動軸之全行程反向誤差。
針對五軸CNC工具機中轉動軸之靜態誤差，本論文中使用六維運動量測系統量得五軸CNC工具機中2轉動軸共8項靜態誤差，並利用CNC控制器中之靜態誤差補償功能，由不同量測方法驗證所量得之結果，實驗結果顯示使用六維運動量測系統可成功量出五軸CNC工具機轉動軸之靜態誤差。
