振動輔助切削是近年來新興的一種切削加工技術，藉由振動裝置使刀具與工件間產生高頻率、微小振幅的相對運動。與傳統加工相比，具有提升工件表面精度、增加刀具壽命等優點。因應現代科技快速的發展，對於高精度及高產率的要求下，振動輔助切削是個很好的選擇。
本研究主要是以振動輔助應用於微銑刀(micro mill)的銑削加工作為研究方向。在不同加工參數(切削速度與進給)，觀察及探討微型銑刀在傳統銑削與振動輔助銑削下之刀具磨耗、工件表面精度及毛邊之影響。研究中發現，當振動速度大於切削速度三倍時，可延長刀具壽命。而依據實驗結果，振動輔助切削相對於傳統切削，工件表面精度在進給4 μm/rev、切削速度3.39 m/min的加工條件中為提升最多的43.51 %。而振動輔助切削的導入，亦有抑制毛邊生成的作用。在振動輔助切削加入微量潤滑(MQL)可有效改善振動輔助切削因摩擦增加導致切削力過大刀具斷裂的情形，在提升工件表面精度及抑制毛邊生成皆有很好的表現。

Vibration assisted cutting (VAC) is a new metal machining technique in recent years, where high-frequency and low-amplitude vibrations are imposed to the cutting tool or the workpiece. It has many advantages than conventional cutting (CC), especially improvements in surface finish and tool life. Nowadays, the use of VAC is a good strategy for micro-machining due to long tool life and high product dimension accuracy.
This study presents an experimental investigation of the VAC in micro milling. The tool wear, surface roughness, and burr formation are investigated for different cutting parameters under conventional and vibration assisted cutting. When the vibration speed is higher than 3 times of the cutting speed, the tool life can be prolonged in this study. The experimental results show that VAC process has better surface finish (43.51% reduction in value) compared to that in CC, when the cutting conditions are feed of 4 μm/rev and cutting speed of 3.39 m/min. It is also found that VAC can diminish the formation of burr formation. By introducing MQL to VAC, the tool life is extended because the MQL could reduce the friction between the tool and workpiece.
