Background

The thin-wall parts are more and more widely applied, and have the characteristics of light weight, material saving, compact structure and the like. However, the inventor of the utility model discovers that the thin-wall part has poor rigidity, weak strength and small clamping reference surface, and is easy to deform due to stress and vibration in the cutting process, thereby influencing the processing quality and processing precision of the part. The stressed deformation means that the thin-walled part is not easy to clamp, the workpiece wall is thin, and clamping deformation is easy to generate under larger clamping pressure; vibration deformation refers to the fact that in the high-speed cutting process, a workpiece is easy to vibrate, so that the shape and position precision and the surface roughness of the workpiece are affected.
