随着航天、航空及生物工程的不断发展,钛合金材料的应用范围不断扩大,因此对其加工工艺的研究也不断深入,特别是钛合金的超精密加工。钛合金具有熔点高(1670℃),比重轻,比强度大,热导率低,常温回弹性大,耐蚀性好等特点,钛又属化学活泼性较大的元素,易与氧、氢、氮、碳等形成稳定的化合物。钛及其合金的上述性质,给其切削加工带来了很多不利因素。 1)、钛合金的低热导率造成切削过程散热差,切
With the continuous development of aerospace, aviation and bioengineering, the application range of titanium alloy has been expanding continuously. Therefore, the research on its processing technology has been deepened, especially the ultra-precision machining of titanium alloy. Titanium has the characteristics of high melting point (1670 ℃), light weight, high specific strength, low thermal conductivity, large room temperature rebound resilience and good corrosion resistance. Titanium is also characterized by its large chemical activity. , Nitrogen, carbon, etc. to form stable compounds. The above properties of titanium and its alloys, to the cutting process has brought a lot of unfavorable factors. 1), low thermal conductivity of titanium alloy cutting process caused by poor heat, cut
