Firstly, the reduction of machining accuracy caused by internal factors can lead to machining deformation of parts.

In the process of machining parts, we usually use lathes for machining operations.According to the analysis of work experience, we will place the processing parts on the chuck of the lathe, let the chuck clamp the parts, and then use the centripetal force of the lathe to carry out the lathe operation on the parts.

Secondly, processing operations after heat treatment can lead to deformation of parts.

Normally, parts after heat treatment processing, if not to eliminate stress, will cause the parts within the internal stress, if in the process of eliminating stress, the internal stress imbalances, will cause a deformation of the parts, parts appear deformation, the main parts of internal stress is to balance.

Finally, the elastic deformation caused by external factors can lead to the deformation of parts.

In the process of parts processing, the processing deformation caused by elastic deformation mainly has three forms, first of all, there are parts processing process containing cantilever form or thin sheet form, this will largely lead to the location of the parts is not firm, resulting in the clamping is not fixed, elastic processing deformation of parts.
