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.
1. The external specification parameters of CNC machining
The specific specifications of the surface itself or the middle of the surface after CNC parts processing are in line with the ideal part specifications. The ideal part processing specification refers to the median value of the specification indicated on the part drawing.
2. Shape accuracy parameters of CNC machining
The specific shape of the surface of the CNC part after machining is consistent with the ideal surface shape of the part. The ideal part surface shape refers to the certain surface geometry shape.
3. Partial accuracy parameters of CNC parts processing
After the CNC parts are processed, the specific parts of each surface are consistent with the parts between the surfaces of the ideal part. The part between the surfaces of the ideal part refers to the certain part between the surfaces.
