Causes of deformation in machining of mechanical parts
1. The machining accuracy of parts is changed due to internal force
In the process of lathe machining, it is usually to use the centripetal force to clamp the parts with the three jaw or four jaw chuck of the lathe, and then process the mechanical parts. At the same time, in order to ensure that the parts are not loose when subjected to force and reduce the role of internal force, it is necessary to make the clamping force greater than the cutting force of the machine. The clamping force increases with the increase of cutting force, and decreases with the decrease. Such operation can make the mechanical parts stable in the process of processing. However, after the three jaw chuck or four jaw chuck is loosened, the machined mechanical parts will be far different from the original ones, some of which are polygonal, and some are elliptical, with large deviations.
2. Deformation is easy to occur after heat treatment
For mechanical parts of the thin type, due to their large length diameter, straw hats are prone to bend after heat treatment. On the one hand, there will be bulge in the middle, and the plane deviation will increase. On the other hand, due to various external factors, parts will be bent. These deformation problems are not only caused by changes in the internal stress of the parts after heat treatment, but also due to the lack of solid professional knowledge of the operators, who do not know much about the structural stability of the parts, thus increasing the probability of part deformation.
3. Elastic deformation caused by external force
There are several main reasons for elastic deformation of parts in machining. First, if the internal structure of some parts contains flakes, there will be higher requirements for the operation method. Otherwise, when the operators locate and clamp the parts, they cannot correspond with the design of the drawings, which may easily lead to elastic deformation. Second, the unevenness of the lathe and fixture makes the force on both sides of the part uneven when fixing, resulting in the translation and deformation of the part on the side with less force during cutting. Third, the positioning of the parts in the processing process is unreasonable, which reduces the rigidity and strength of the parts. Fourthly, the existence of cutting force is also one of the causes of elastic deformation of parts. The elastic deformation caused by these different reasons shows the influence of external force on the machining quality of mechanical parts.
