摘　　要：钛合金材料以轻质、高强、耐腐蚀等优异特性在航空航天领域得到了广泛的应用,但良好的材料属性也为其加工带来难题,尤其对结构复杂的钛合金框架类零件切削,对刀具的设计、使用和性能评价都提出了更高的要求。首先分析了限制钛合金框架类零件切削性能发挥的影响因素,即切削力、切削温度和已加工表面残余应力,并以影响因素为约束总结了钛合金框架类零件加工用整体立铣刀几何结构、表面涂层和基体材料的研究现状;其次针对特定加工场景以影响因素为约束推荐了切削参数;随后将影响因素量化为便于识别统计的评价指标,即切削寿命、效率和表面完整性,进而阐述了刀具切削性能评价的研究进展。最后对整体立铣刀在钛合金框架类零件加工领域的发展与应用进行展望。随着新一代信息技术发展,将进一步推动刀具设计、使用与切削性能发挥的深度融合,助力钛合金框架类零件的高质量、长寿命、高效率切削。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.
