钛由于其固有特性而难以加工。在先前的研究中，钛的可切削性通过与银合金化而得到改善。本研究旨在通过计算机辅助设计和计算机辅助制造系统，评价使用Ti-20%Ag合金和钛制造框架后碳化钨布尔斯的耐久性。两种金属的磨损面积比存在显著差异。与钛相比，实验Ti-20%Ag合金的机加工布尔斯的磨损面积比显著更低。随着加工次数的增加，钛和Ti-20%Ag的磨损面积的差异变得显著。结果表明，相同的布尔斯钻头使用Ti-20%Ag的时间比使用纯钛的时间更长。因此，就刀具寿命而言，Ti-20%Ag合金的切削性能优于钛的切削性能，这是上级的。
Titanium is difficult to machine because of its intrinsic properties. In a previous study, the machinability of titanium was improved by alloying with silver. This study aimed to evaluate the durability of tungsten carbide burs after the fabrication of frameworks using a Ti-20%Ag alloy and titanium with a computer-aided design and computer-aided manufacturing system. There was a significant difference in attrition area ratio between the two metals. Compared with titanium, the ratio of the area of attrition of machining burs was significantly lower for the experimental Ti-20%Ag alloy. The difference in the area of attrition for titanium and Ti-20%Ag became remarkable with increasing number of machining operations. The results show that the same burs can be used for a longer time with Ti-20%Ag than with pure titanium. Therefore, in terms of tool life, the machinability of the Ti-20%Ag alloy is superior to that of titanium.
