In the machining industry, CNC processing is also known as computer gong processing. It refers to the processing steps that are completed by the NC command of the programmer. Now let’s take a look at the accuracy parameters of CNC machining. It is mainly the level that the specific geometric parameters (specification, shape and position) of CNC parts are consistent with the ideal geometric parameters. Detailed understanding of the following parameters:
In the process of machining mechanical parts and small batch parts, CNC machining accuracy usually includes three levels of parameters: specification accuracy, shape accuracy and position accuracy.
- Shape and specification parameters of CNC machining
The specific specification of the surface itself or the middle of the surface after machining of CNC parts is consistent with that of the ideal part. The ideal part processing specification refers to the median value of the specification indicated on the part drawing.
- Shape precision parameters of CNC machining
The specific shape of the machined surface of CNC parts is consistent with that of the ideal parts. The ideal surface shape of a part refers to the positive surface geometry shape.
- Position precision parameters of CNC parts processing
After CNC parts are processed, the specific parts of each surface are consistent with the parts of each surface of the ideal parts. The position between the surfaces of ideal parts refers to the positive position between the surfaces.
The above is the precision parameter control of CNC machining. For different shapes, shapes, simplicity and complexity, it is necessary to select appropriate processing parameters to improve CNC machining efficiency and ensure the machining accuracy of parts.
