隨著微切削技術在微製造的應用領域的不斷擴大與刀具材料之選擇限制,微刀具磨耗在加工中更形快速。由於刀具直徑減小,剛性相對降低,刀具磨耗量對切削品質的影響也較傳統切削顯著。為了探討刀具磨耗對切削動態系統之影響,本文使用有限元素軟體建構微型銑刀切削系統模型,整合銑削力、犁切力與刀腹運動作用力,模擬刀具磨耗量增加對切削振動系統之影響,觀察分析其時頻域切削力與加速度訊號的變化,並與實驗量測出來的數據做比較驗證。由實驗與模擬結果顯示,兩者頻域響應低頻主要峰值頻率均位於1.6kHz,另外,隨著刀具磨耗量增加時,時域振動訊號之振幅均有變大趨勢,在頻域上,模擬刀具振動能量會往高頻轉移的趨勢,工件振動實驗訊號則在各個頻率均有能量升高的情形。
