What are the factors that affect the machining accuracy in precision parts machining

latest company news about What are the factors that affect the machining accuracy in precision parts machining  0
In the field of precision parts processing, a complete system consisting of machine tools, fixtures, workpieces and tools is called a process system. In the process of machining, the relative position of the workpiece and the tool determines the size, shape and position of the part. Therefore, the problem of machining accuracy also involves the accuracy of the entire process system. Various errors of the process system will be reflected as geometric errors of the processing system in different ways and programs under different conditions during the processing. According to the nature of the process system error, it can be summarized as the geometric error of the process system, the error caused by the force deformation of the process system and the error caused by the internal stress of the workpiece.
