本研究主要探討使用碳化鎢刀具車削Ti-10V-2Fe-3Al之切削性質，使用田口法設計本研究之切削參數，探討各切削特性與其因子間之影響程度，本研究之實驗因子分別為切削速度60、80及100 m/min，每轉進給0.1、0.2及0.3 mm/rev，切深為0.2、0.3及0.4 mm。根據實驗結果，分析因子影響程度如下：當切削速度60、80及100 m/m時切削剪切應力τ範圍坐落在630 ~ 690 Mpa之間。對於刀腹磨耗，刀具磨耗的部分將使用刀腹磨耗量與材料移除量之比值做為結果分析，其結果顯示，切削速度越慢，每轉進給越小，切深越小，能夠獲得越好的刀具磨耗。表面粗糙度部分結果顯示，每轉進給越小，切深越小，切削速度越快，能夠獲得較佳之表面粗糙度。

This thesis will also focus on above two dimensions by exploring the cutting properties of Ti-10V-2Fe-3Al using WC tools, building up a model of cutting parameters to explore the interaction between each cutting characteristic and its factors by using Taguchi method. The thesis use cutting speed of 60, 80 and 100 m/min; feed 0.1, 0.2 and 0.3 mm/rev; depth of cut are 0.2, 0.3 and 0.4 mm as experimental factor.According to the results, range of shear stress τ locate between 630 ~ 690 N / mm2 for cutting speed. For flank wear and tool wear, using the ratio of tool wear and the cutting volume. Experiment outputs shows that slower cutting speed, smaller federate and deapth of cut lead you to he better tool wear. For surface roughness, it shows that the smaller feedrate, the smaller depth of cut, and the faster cutting speed lead you to better surface roughness.
