What are the reasons for deformation and improvement during the processing of parts?

In the industry of processing parts, the most taboo problem is the deformation of parts; as soon as it appears, the consequences will be unpredictable, which will affect the economic efficiency of the enterprise, and secondly, it will cause a number of safety issues that will make enterprises panic. What is the cause of the deformation of parts? How can it be improved?
Basically, these are the following points:
Internal forces lead to changes in the accuracy of part processing. Technicians know that during processing, the part is clamped by three jaws of the lathe, ensuring that during processing, the part is subjected to stable force; over time, this will lead to the loosening of the lathe chuck, so the stress on the part decreases, resulting in deformation.
2. Heat treatment can easily lead to deformation. When processing some thin and small parts, they are usually heat-treated first; due to the inexperienced technical staff, they may not fully understand the structural characteristics of these parts, making it easy for the parts to become bent.
3. Processing parts under the influence of external forces leads to elastic deformation. During part processing, lathes and fixtures are often used, and when they are uneven, they appear in stationary parts; when the stress is uneven, the side with less stress deforms.
Measures for improvement:
Firstly, after the heat treatment of parts and their natural deformation, use professional cutting tools for finishing to ensure the perfection of the parts.
Secondly, carry out technological innovations to increase the rigidity of the parts.
Technical staff should improve technology, increase innovations, choose the appropriate method of heat treatment, and change the rigidity of the parts so that they are not prone to deformation.
