摘要
在航空工业,钛合金用量常被作为衡量飞机选材先进程度和航空工业发展水平的重要指标之一。钛合金的优异性能也给钛合金的加工带来了巨大困难,钛合金航空结构件更是面临着材料自身难加工与工件结构复杂难加工的双重挑战。对钛合金加工刀具与工艺技术国内外研究现状进行综述,阐述目前制约钛合金高效加工瓶颈难题,介绍了钛合金加工新技术及其发展趋势。
In aviation industry,the usage amount of titanium alloys is often regarded as one of the most important indicators to measure the advantages of aircraft materials selection and the development of the aviation industry.However,the excellent properties of titanium alloys also bring great difficulties to processing them.Difficult-to-machine materials and difficult-to-machine structures are the two challenges in the process of machining titanium alloy aeronautical structural parts.This paper summarizes the current research status of the cutting tool and processing technology of titanium alloys components at home and abroad.Then the current bottleneck problems restricting the efficiency of processing of titanium alloys are presented.Finally,the new technology of titanium alloy processing and the development trends are summarized.
