Problems solved by technology

[0003] After retrieval, CN102275131 discloses a monitoring method and monitoring system for detecting the processing state of a grinding machine, which uses a sonar sensor to receive the sonar signal sent by the CNC grinding machine when the workpiece is processed, and converts the sonar signal into an electrical signal. The acoustic detection system converts the detected electrical signals output by the sonar sensor into RS232 communication protocol signals and RPOFIBUS communication protocol signals, and transmits the RS232 communication protocol signals to the CNC system on the grinding machine, and the CNC system converts the received RS232 protocol signals The signal is displayed on the screen in the form of a dynamic waveform, and its substantial disadvantage is that the sonar waveform displayed on the screen of the numerical control system by this method must be understood by a professional process engineer. The smoothness of the waveform is used to analyze the rationality of the process, to analyze the process and error information of the workpiece, to guide the production and modify the processing process, but not to allow the operator to intuitively see whether the workpiece is qualified or not, resulting in low work efficiency
