Processing of mechanical parts

In the processing industry, it is normal for some errors to occur when processing a product, because just how to avoid them, there may be errors, because it is impossible to achieve perfection, even if humans are the same, it is impossible to have perfect people. , The machining of mechanical parts is one of them, so what errors are prone to occur in the machining of mechanical parts.

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 measurement accuracy is directly affected by the measurement method, the accuracy of the measuring tool, the workpiece, and the subjective and objective factors.

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.

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.

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 are the errors that are prone to occur in the processing of mechanical parts. During processing, there are five kinds of errors. When processing, we must be careful. Although we can't avoid these situations, we can do it well. NS.
