摘　　要：钛合金因其比强度高、高温强度高等优异性能广泛应用于航空航天领域,是航空结构件的主要材料之一。但是由于钛合金的难加工性,加工过程中切削参数较低,刀具易磨损,切削过程稳定性差,严重制约了航空结构件的生产效率。为了实现钛合金结构件高速高效加工,本文基于生产实践,以钛合金切削冷却方式、切削力均衡优化以及刀具轨迹质量稳定性等关键技术作为突破口,进行详细阐述,并应用于结构件生产过程。Titanium alloy is widely used in aerospace industry because of its excellent performance, such as high specific strength and high temperature strength. It is one of the main materials of aeronautical structures. However, due to the difficult workability of titanium alloy, machining efficiency of aeronautical structures is restricted by lower cutting process parameters, tool wear and poor cutting process stability. In order to improve cutting speed and machining efficiency of Tialloy aircraft parts, the influence of cooling methods on high efficiency, resource leveling optimization of the cutting force and stability of toolpath generation quality are summarized to provide reference for high-efficieny machining.
