刀具是製造業不可或缺的工具，近年來手機蓬勃發展使得手機外殼採用各式各樣的材料，例如鋁合金、鈦合金、塑膠材料等。本論文主要是設計刀具幾何以提升刀具在銑削Al7003時的刀具壽命與工件的表面品質。首先，刀具幾何最佳化是使用田口法L9(34)直交表做配置，控制因子為端銑刀的徑向切削角、徑向離隙角、軸向切削角、軸向離隙角，實驗目標為增加刀具壽命、減少刀腹磨耗與工件之表面粗糙度，再經由變異數分析與多品項分析結果。
第二部分刀具幾何最佳化，使用田口法L18(34)直交表做配置，以第一部分的實驗結果經由變異數分析與多品項分析後發現，影響工件表面粗糙度的主要因子為「切削角」，而徑向離隙角對表面粗糙度的影響不大，因此控制因子更改為徑向切削角、緣刃、軸向切削角、軸向離隙角。其結果為緣刃與切削角影響較大。

Cutting tools are an indispensable tool for the manufacturing industry. In recent years, the development of mobile phones has enabled mobile phone housings to use a variety of materials, such as aluminum alloys, titanium alloys, and plastic materials. This paper mainly designs the tool geometry to improve the tool life and the workpiece surface quality when milling the Al7003. First, tool geometry optimization is performed using the taguchi L9(34) orthogonal array. The control factor is the “radial rake angle”, “radial relief angle”, “axial rake angle”, and “axial relief angle” of the end mill. The goal is to increase the tool life, reduce the blade wear and the surface roughness of the workpiece, and then through the Analysis of variance and results of multi-item analysis.the second part of the tool geometry optimization, using the taguchi L18(34) orthogonal array. Based on the first part of the experimental results through the Analysis of variance and Multi-item analysis, it was found that the main factor affecting the surface roughness of the workpiece is the “rake angle”, and the radial relief angle has little effect on the surface roughness. Therefore, the control factors are changed to “radial rake angle”, “margin”, “axialrRake angle” , and “axial relief angle”.
