Description
Technical Field
The invention belongs to the technical field of machining, and particularly relates to a machining method for a thin-wall circular ring part.
Background
As shown, a typical thin-walled ring-shaped component is made of copper alloy. The part has low strength and thin wall thickness, is easy to generate clamping and processing deformation in the processing process, and is a relatively difficult problem in turning processing. The product processed by the processing method has extremely high rejection rate for the following reasons:
1. deformation is easily generated under the action of clamping pressure, so that the dimensional accuracy and the shape accuracy of the workpiece are influenced;
2. the cutting heat causes thermal deformation of the workpiece, making the workpiece size difficult to control;
3. under the action of cutting force (especially radial cutting force), vibration and deformation are easy to generate, and the dimensional accuracy, the shape, the position accuracy and the surface roughness of the workpiece are influenced.
In conclusion, the thin-wall part has poor rigidity and strength, high metal cutting removal rate and high possibility of deformation in the machining process in the conventional machining method, so that the form and position errors of the part are increased, and the machining quality of the part is difficult to ensure. Therefore, it is desirable to provide a machining method with high metal cutting removal rate, which can reduce or even eliminate machining deformation, so as to reduce the rejection rate of product machining and improve the machining efficiency.
