摘　　要：薄壁铝制零件在数控加工中容易发生零件变形、折断现象。文中利用因果图分析出零件变形的可能影响因素,找出主要原因是加工工艺不合理和零件装夹方式不合理,然后通过理论分析修改装夹方式、调整加工工艺。薄壁铝制零件的加工合格率明显得到了提升。In NC processing of thin -walled aluminum parts, deformation and fracture often occur. Causal diagram analysis is used to obtain latent deformation factors. The main deformation factors are unreasonableprocessing method and fixture. This paper improves the clamping method and processing method. The qualified rate of the thin wall aluminum parts is improved obviously.
