铝合金与大多数材料相比,本身比重小、抗腐蚀性强且具有良好的导热及导电特性,加上具备优秀的机械与物理性能等,在航空制造领域有着广泛应用。铝合金加工制造过程中主要应用切削加工手段,但会在零部件中残留应力造成变形,直接影响零部件精度。因此必须采取有效措施规避零部件生产过程中的残余应力变形问题,提高产品精度与质量。本文中笔者航空发动机生产为切入点,分析解决铝合金零部件加工变形问题的措施。
Compared with most materials, aluminum alloy has a small proportion of its own, corrosion resistance and good thermal conductivity and electrical conductivity, coupled with excellent mechanical and physical properties, has a wide range of applications in the field of aviation manufacturing. Aluminum alloy processing and manufacturing process is the main application of cutting tools, but the residual stress in the parts caused by deformation, a direct impact on the accuracy of parts. Therefore, we must take effective measures to avoid parts of the production process of residual stress and deformation problems, improve product accuracy and quality. In this paper, the author of aeroengine production as a starting point, analysis and solution of aluminum alloy parts processing deformation measures.
