摘要: 
切削是機械加工中非常重要的一個步驟,並被廣泛地用於製造產業。切削加工過程中影響常受切削時產生的顫振所困擾,切削顫振會造成刀具與工件間的相對振動,使得加工品質降低,甚至破壞加工設備,故如何避免切削顫振為一迫切的課題。雖然文獻提出諸多不同避免切削顫振的方法但大多不夠準確,本研究以敲擊實驗獲得之系統參數為參考,進行實際切削求得在不同轉速下的臨界切深,並且透過最小平方法進行系統的參數鑑別,求得在不同轉速下,系統參數的變化,並以此調整切削穩定圖,令使用者有其更精準的依據,以避開顫振。本研究探討之方法進一步在加工中心機以及CNC車床驗證銑削與車削之適用性,結果顯示以本方法調整之切削穩定圖可較精準地吻合加工數據。

Cutting is one of the most fundamental machining processes and has been widely applied in industrial practice. While cutting is often bothered by chattering that generates vibration between the cutting tool and the workpiece thus downgrades the process quality and even damage the machine tools, it has been an issue how to overcome the chattering problem. Chattering is represented by the cutting stability lobe which indicates the limit of depth of cut for stable cutting at each spindle speed or cutting speed. Although various methods have been proposed to avoid the chattering in the cutting process, most of them are unable to predict the chattering precisely. In this study, cutting system parameters and stability lobe are improved based on machining data with system parameters obtained by modal testing as a reference. The machining data are the critical depth of cut at different cutting speeds. Cutting system parameters at different speed are calculated by least error square fit. Stability lobe is then adjusted based on the new system parameters. Two tests, a milling test and a turning test, are performed based on the proposed method for verification. The improved stability lobe is a good guide for engineers to avoid chattering
