The sound and noise diagnosis technology for fault maintenance of CNC machine tools includes direct monitoring and indirect monitoring. Direct monitoring is the "auditory diagnosis" in practical diagnostic technology. In modern diagnostic technology, noise diagnosis refers to indirect monitoring, which involves diagnosing the "quantity" of faults based on the sound signals collected by sensors and processed through data processing. Sound diagnosis can achieve good results for mechanical faults with periodic motion, such as high-precision gears and bearings, wear of hydraulic valves, etc.

Online and offline diagnosis of CNC machine tools
Online diagnosis refers to the automatic testing and inspection of CNC devices, PLC controllers, servo systems, PLC inputs/outputs, and other external devices connected to the CNC device in real-time through the control program of the CNC system, while the system is in normal operation, and displays relevant status and fault information. In addition to displaying the alarm number and alarm content on the screen, the system also displays the status of NC internal flag registers and PLC operating units in real time, providing great convenience for fault diagnosis.
