五軸同動CNC工具機中的三線性軸可用雙球桿循圓量測儀(DBB)檢驗動態誤差,但是針對旋轉軸動態誤差尚未有標準量測方法。針對五軸同動CNC工具機旋轉軸動態誤差量測,本實驗室已提出新的量測方法:在旋轉軸的同動工作空間中找出適當的量測圓路徑,使原本用於量測工具機線性軸動態誤差的DBB量測工具,可量測到單純由兩旋轉軸同動產生的動態誤差。三線性軸標準DBB檢驗方法,再加上本實驗室已發展的雙旋轉軸DBB動態誤差量測方法,五軸工具機全機五軸的動態誤差量測尚缺線性軸搭配旋轉軸的動態誤差量測。
本論文建立五軸同動CNC工具機完全動態誤差量測方法( Total Dynamic Test , T.D.T),首先針對線性軸搭配旋轉軸的動態誤差量測方法,設計同動空間之量測圓路徑,分析DBB量測靈敏度,決定最佳化之量測參數,並模擬理想軸動態模型下各項動態誤差所對應之量測圖譜,然後依五軸同動工具機各兩兩軸組合之可能性,提出三種完全動態誤差量測方法,包括檢驗性完全動態測試(Inspective TDT),調校性完全動態測試(Consequent TDT),確認性完全動態測試(Confirmation TDT)最後,並以實機測試證實此量測方法之可行性。
此首創之”五軸同動CNC工具機完全動態誤差量測方法”結合DBB雙線性軸及雙旋轉軸之DBB量測方法,設計可能之旋轉軸及線性軸組合之最佳DBB循圓量測順序及位置控制迴路增益調整機制,大幅改進五軸同動CNC工具機之動態精度。
