鋁合金為工業當中普遍使用之被加工材之一，因為鋁合金具有比鐵較輕之重量，且為面心立方結構體，所以擁有很高的可塑性，容易加工成形並製作成各式板材。隨著科技時代之進步與經濟快速成長，產品的需求也開始多樣化，鋁合金被當作加工材的使用率也隨之大幅提升。但是隨著加工技術慢慢成形，業者開始對於加工完成後之成品不再只有尺寸之要求，表面處理也開始隨之要求越來越高與嚴苛，像是iPhone 7的邊框就是使用鋁合金材質所製成，其邊框不希望是粗糙的，故鏡面加工方式對工件表面品質相當要求，機台、切削參數、工件的材質及使用刀具幾何等都會影響加工之結果，但又以刀具之影響最大，所以本文探討刀具幾何能在切削時，產生較好之加工面。
本文實驗是使用端銑刀以側銑方式加工鋁合金時，加工完成後之表面會產生光澤度不一之橫向拉紋，也就是一般業界俗稱的陰陽面，如有橫向拉紋加工業者必須再多一個程序，即使用拋光機做拋光或是磨輪將它磨掉，這相當費時費工，所以本文使用田口實驗法以不同的控制因子與水準取得較佳的參數值，進而使得端銑刀刀刃口有較佳的平整度，於加工完成後可以減少鋁合金工件的表面橫向拉紋。

Aluminum alloy is one of the processed materials commonly used in the industry. Because aluminum alloy has the lighter weight than iron also because the aluminum alloy is face-centered cubic structure, it has high plasticity and is easy to be used in processing and forming into various shapes, plate material. With new technological advances, the demand for fast growing products has begun to diversify. Also have the advantages of light weight, easy processing, and non-corrosive effects, the use of aluminum alloy as a processed material has also increased dramatically. However, as the processing technology is gradually fully developed, the industry is no longer just the size requirement for the finished product after the processing is completed. The surface treatment has also been increasingly demanding and demanding, such as the border of the iPhone 7 is the use of aluminum alloy material made of raw materials, and nobody wants to get the rough edges. The machine factors, cutting parameters, materials, and tool geometry affect a mirror finish of workpieces. However, the cutting tools have the greatest impact. Therefore, the experimental tool geometry to achieve cutting, can produce better processing surface.
This experiment is aimed at the use of side milling for processing aluminum alloy by end mills. The surface after processing will have a different degree of gloss of horizontal pull patterns, which are commonly known in the industry as the dark and light stripes. It is very time-consuming and laborious for an operator to have to process more than one process and have to use a polisher to polish it or use a grinding wheel to polish it. Therefore, this experiment explores how to use tool geometries to improve the machining process and reduce machining after finishing the surface of the horizontal pull patterns.
