本研究係以實驗的方式探討鋁合金7075-T7351材料，以二種碳化鎢刀具在不同因子(轉速、進刀量、進給率)水準下以車削加工方式求得最小表面粗糙度之最佳化切削參數。
本實驗之規劃是利用田口式實驗直交表以及統計手法進行實驗的規劃，期以較少之實驗組數獲取不同因子交互作用與加工表面粗糙度之關係，文中運用田口法中之直交表規劃實驗參數之配置，此實驗之規劃法除可獲得在控制因素水準範圍內，使達到粗糙度之最佳化切削條件外，並可建立粗糙度和各實驗因子之預測模式，以提供切削前之預測加工結果再經由實驗結果的分析可研判出各控制因素對粗糙度的影響。
經由24因子設計，以隨機編排實驗順序逐一執行切削加工，再以L16(215)直交表計算平方和及效果，之後以ANOVA表觀察交互作用求得最佳水準為轉速1400rpm、進刀量0.67mm、進給率0.051mm/rev及刀具1 。

This thesis has adopted experimental method to research aluminum alloy 7075-T7351 material. The major research has been focused on obtaining the minimum surface roughness and the optimal cutting parameters for turning process, while using two kinds of carbide tools under different factor standards, i.e. spindle speed, depth of cut & feed rate standard.
This experiment has used Taguchi experiment orthogonal array and statistic as research method, in order to use less experiment groups to obtain the intersection of different factors and the relationship of process surface roughness. In the experiment, the Taguchi experiment orthogonal array parameters allocation has been used. Under the controlled factors standard, apart from the obtain of roughness optimal cutting, this experiment can establish roughness and experimental factors predict model as well. As a result, the result is able to be predicted before the cutting process. Through analyze of experimental result, it is available to judge the influence of each controlled factors to the roughness.
Through the design of 24 factors, random arrangement sequence has been checked one by one to perform the cutting process. Afterward, L16 (215) orthogonal array has been used to calculate the sum square and the effectiveness. And then ANOVA diagram was used to observe the intersection and to obtain the optima standard, which spindle speed is 1400 rpm, depth of cut is 0.67 mm, feed rate is 0.051mm/rev and carbide tool is 1.
