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