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.
