What errors are prone to occur in the processing of mechanical parts?

Nowadays, with the continuous development of society, people's living standards have improved significantly. We often come into contact with the processing of mechanical parts and accessories. Its arrival has brought great convenience to our lives. Sometimes, due to the improper method we use, the machining of mechanical parts is prone to errors. What should we do at this time? Today, the editor will come to learn with everyone what errors are prone to occur in the processing of mechanical parts, as follows:
1. Positioning error: Positioning error mainly includes datum misalignment error and positioning pair manufacturing inaccuracy error.
2. Measurement error: When measuring parts during processing or after processing, the measurement accuracy is directly affected by the measurement method, the accuracy of the measuring tool, the workpiece, and the subjective and objective factors.
3. Tool error: Any tool will inevitably wear out during the cutting process, and this will cause the size and shape of the workpiece to change.
4. Fixture error: The function of the fixture is to make the workpiece equivalent to the tool and the machine tool have the correct position, so the geometric error of the fixture has a great influence on the machining error (especially the position error)
5. Machine tool error: including spindle rotation error, guide rail error and transmission chain error. Spindle rotation error refers to the variation of the actual rotation axis of the spindle relative to its average rotation axis at each moment, which will directly affect the accuracy of the processed workpiece.
The above is a brief introduction of the editor on the errors that are prone to occur in the processing of mechanical parts. For details, please consult this site.
