Method and system for intelligent monitoring of cnc processing based on industrial internet of things

A system for intelligent monitoring of computer numerical control (CNC) processing based on an Industrial Internet of Things (IoT), comprising a user platform, a service platform, an industrial IoT management platform, a sensor network platform, and a perception control platform, the industrial IoT management platform includes a production process management sub-platform, a data center, and a device management sub-platform, wherein the industrial IoT management platform is configured to:

• obtain, based on an input device of the perception control platform, information to be processed corresponding to a task to be processed;
• determine a CNC processing parameter and simulated processing data corresponding to the CNC processing parameter by performing a CNC process simulation based on the information to be processed, the CNC processing parameter including a tool feed step length;
• control a CNC processing device of the perception control platform to perform the task to be processed based on the CNC processing parameter;
• collect actual processing data during a performance of the task to be processed according to a monitoring frequency by a monitoring device of the perception control platform;
• perform a deviation determination on the actual processing data and the simulated processing data;
• in response to that a result of the deviation determination satisfies a preset alert condition,
• generate a processing alert instruction and send the processing alert instruction to an alert device of a user platform;
• and
• control the CNC processing device to adjust the tool feed step length based on the actual processing data.
