Abstract:High quality and high efficiency machining of titanium alloy structural parts has always been an important bottleneck restricting the rapid development of aircraft. The typical characteristics of titanium alloy that were prone to quality problems in the process of processing were classified, the processing technology of each typical characteristic was analyzed, and the corresponding processing technology scheme was, designed for each typical characteristic. Combining with the specific processing application of the research results in actual parts, it provides reference for titanium alloy processing, especially for the processing of related typical characteristics.
