The amount of deformation is proportional to the complexity of the shape, the aspect ratio and the wall thickness, and is proportional to the rigidity and stability of the material. Therefore, the influence of these factors on the deformation of the part should be minimized when designing the part.
Especially in the structure of large parts, the structure should be reasonable. Defects such as blank hardness and porosity should be strictly controlled before processing to ensure blank quality and reduce the deformation of parts caused by it.
When the clamping force in several directions acts on the part, the sequence of the clamping force should be considered. The clamping force should be applied first to make the part contact the support, and it is not easy to be too large. The main clamping force to balance the cutting force , should act last.
Secondly, it is necessary to increase the contact area between the part and the fixture or use the axial clamping force. Increasing the rigidity of the parts is an effective way to solve the clamping deformation, but due to the characteristics of the shape and structure of thin-walled parts, they have low rigidity. In this way, under the action of clamping force, deformation will occur.

Increasing the contact area between the part and the fixture can effectively reduce the deformation of the part when clamping. Designing and making a special fixture can make the clamping force act on the end face, which can solve the bending deformation of the part caused by the thin wall and poor rigidity of the part. In addition, the cutting amount is reasonably selected, so as to achieve the purpose of reducing the deformation of the parts.

For large parts, profiling should be used, that is, the deformation of the parts after assembly is estimated, and the deformation is reserved in the opposite direction during processing, which can effectively prevent the deformation of the parts after assembly.

To sum up, for the easily deformed parts, corresponding countermeasures should be adopted in the blank and processing technology, and a suitable process route will be found according to different situations. Far East Tech Technology has rich experience in precision machining, which can effectively avoid deformation during machining. If you need to know more, please contact us.
