Processing of mechanical parts and accessories Processing of mechanical parts and accessories: What are the errors that are easy to appear in the process of processing?

In the factory, the processing of mechanical parts is absolutely indispensable. In the factory, its use range is very wide. In the process of processing, it is inevitable that some difficulties will occur, so in the process of processing, it is easy to appear. What are the errors?

Positioning error: Positioning error mainly includes fiducial misalignment error and positioning pair manufacturing inaccuracy error.

Measurement error: When measuring parts during processing or after processing, the measuring method, measuring tool accuracy, workpiece and subjective and objective factors directly affect the measurement accuracy.

Tool error: Any tool will inevitably wear out during the cutting process, causing the size and shape of the workpiece to change.

Fixture error: The function of the fixture is to make the workpiece equivalent to the tool and the machine tool have the correct position. The geometric error of the fixture has a great influence on the machining error.

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 the processing of mechanical parts. In the process of use, errors are easy to appear. In the process of processing, these are the things to pay attention to. The operator must know whether it will appear these questions.
