Zhang Wenjian，Yang Song

Abstract:According to the characteristics of thin wall aluminum alloy thin shaft parts are easy to process deformation，the causes of machining deformation are described in detail.By changing the corresponding machining process and other related measures to control the deformation of the workpiece，the size and shape tolerances and surface roughness requirements of the workpiece are ensured.The key step is adopt double top clamping and add the clamping process for auxiliary vise clamping，it has widely practical guiding significance.
