Mechanical parts processing usually have some problems, such as the workpiece deformation in the processing process, how to do, how to do well?
- In order to avoid this kind of deformation, it is necessary to select the appropriate clamping point, and then select the appropriate clamping force according to the position of the clamping point. Therefore, the clamping point and supporting point of the workpiece should be kept as far as possible to make the clamping force act on the supporting part and make the clamping point closer to the processing surface, so as to avoid deformation.
What are the requirements for machining mechanical parts
When the clamping force acts on the workpiece, the order of the clamping force should be considered, and the clamping force should not be too large. In order to balance the cutting force, the clamping force should be applied at the end. It is also necessary to increase the contact area between workpiece and fixture or use axial clamping force. The most effective way to solve the clamping deformation is to improve the stiffness of the parts. The increase of contact area between workpiece and fixture is helpful to reduce the deformation of workpiece in the process of clamping.
What are the requirements for machining mechanical parts
- Workpiece deformation caused by material and structure of workpiece
The deformation is directly proportional to the shape complexity, aspect ratio and wall thickness, and to the stiffness and stability of the material. Therefore, in the design of parts, the influence of these factors on the deformation of the workpiece should be reduced as far as possible. Especially the structure of large parts should be more reasonable. Before machining, the hardness, porosity and other defects should be strictly controlled to ensure the quality of the blank and reduce the deformation of the workpiece.
