doi:10.3901/JME.2023.23.283

Abstract

Abstract: Titanium alloy has been widely used in the aerospace field due to its excellent properties such as light weight, high strength and corrosion resistance, but good material properties also bring difficulties to machining, especially for the cutting of titanium alloy frame parts with complex structures. Higher requirements are put forward for the design, use and performance evaluation of endmill. This study firstly analyzes the influencing factors of the machinability of titanium alloy frame parts, including cutting force, cutting temperature and residual stress of the machined surface, and with the influence factors as constraints, the guidance on the cutting tool geometry, surface coating and material application of endmill for machining titanium alloy frame parts is summarized. Secondly, cutting parameters are recommended for specific machining scenarios with influencing factors as constraints. Then the influencing factors are quantified into evaluation indicators for statistical identification, namely cutting life, efficiency and surface integrity, and then elaborated the research progress of tool cutting performance evaluation. Finally, the development and application of endmill in the machining of titanium alloy frame parts are prospected. With the development of a new generation of information technology, it will promote the deep integration of tool design, use and cutting performance, and help achieve high-quality, long-life and high-efficiency machining of titanium alloy frame parts.
