摘要: 
現今工具機之發展無不朝向高效益、與高功能切削,切削振動變成為一個相當重要之議題。同時,工具機加工不穩定亦源自於顫振的現象。對於顫振之問題,已有多篇文獻探討著重於主軸動剛性方面。本文使用有限元素法,分析軸承-心軸系統與軸承-心軸夾持長刀把刀具時,比較其動態剛性。通常,振動第一模態發生都來自於刀把或刀具懸長造成,在本論文裡,引用了學者所提出之切削穩定性理論,利用電腦程式模擬,建立切削之穩定性圖,來預知加工最佳切削轉速之區域。同時,預測刀具懸長造成的切削穩定圖之區域,做為日後設計上或製造操作參數之參考。並使用頻率響應方式,來量測位於懸長的刀具端點上實驗結果與有限元素分析結果,進行比對,探討切削不穩定發生的區域。

High efficiency and superior performance are the trend for the development of the machine tools. One of the issues is the problem of cutting vibration. Chattering is a cause of cutting instability. Regarding to the chattering problem, lots of researches have been focused on the dynamic stiffness of the spindle of machine tool. In this research, the finite element method was used to analyze and compare the dynamic stiffness between a standard bearing-spindle system and a bearing-spindle grasps a long collet-chuck and cutter. The first model of vibration is usually caused by excessively length of the cutter or collet-chuck. In this research, machining stability theory by other researchers was referred. Computer simulation program was used to establish the range of stable cutting speeds. The result can be used to determine the operating parameters in design and manufacture. Furthermore, the data from frequency response measurement at tip of the cutting tool can be used to compare and contrast with finite element analysis result in order to find the ranges of cutting speeds which causes instability.
