钛合金攻螺纹技术及丝锥改进外文翻译(中文+英文共5000字)
【摘要】钛合金是一种比重小、强度高、耐腐蚀和耐热等特性的金属结构材料。钛合金攻螺纹切削时刀具极易磨损，刀具寿命很短。通过对钛合金攻螺纹过程受力分析，将丝锥直槽变为螺旋槽，可以使切削热和切削力不至于过分集中于切削刃附近，改善散热条件，也可加强切削刃，减少崩损。

The alloy of titanium attacks whorl technology
and screwtap to improve
[Abstract]  Titanium is of small specific gravity , high strength, strong corrosion resistance and heat resistance ,which are the characteristics of metallic structural materials. Titanium is a kind of material easily tapped cutting tool wear, shorting its using time . Titanium is tapping on stress analysis, tapping directly into the spiral groove that can make cutting heat and force without being unduly concentrated in the vicinity of the cutting edge ,not only  improve heat dissipation, but also strengthen the cutting edge, in order  to reduce losses collapse.
