摘　　要：钛合金材料具有比强度高、变形系数小、热强性、低温韧性、抗腐蚀性和较好的焊接性能等优点,其越来越多地被用于制做飞机起落架结构承力件和紧固件等;但由于其导热系数小、弹性模量小、加工性能差、效率低、易烧伤和变形等缺点的存在,也影响其产品的加工及质量。本文结合多型飞机起落架的科研和生产实践,从材料、设备、人员、工艺规程及加工环境等几个方面进行控制,重点完善优化工艺过程,从而提高了加工效率,节约了制造成本,保证了产品质量。Titanium alloy material has the characteristics like high strength ratio, small deformation coefficient, hot strong resistance, low temperature toughness, corrosion resistance, good welding performance and so on, so it has been more and more used in structure bearing parts, fasteners of aircraft landing gear, etc. , but because of its small coefficient of thermal conductivity and the small elastic modulus, the processing performance difference, low efficiency, easy to burn and deformation, it will make effects on the product processing and quality. This paper combined with the landing gear type of scientific research and production practice, from material, equipment, personnel, process documents, processing conditions and other several aspects to control and optimization of process documents to improve the machining efficiency, and save the production cost, which ensures the quality of products.
