AI Technical Summary

Problems solved by technology

The complexity of CNC technology itself, the diversity of processes and the complexity of processed parts make the specifications and varieties of CNC systems vary greatly, the performance varies greatly, the control parameters are complicated, and the debugging operation is cumbersome. Therefore, once the CNC machine tool breaks down, its Fault diagnosis and maintenance will be a highly professional work, and in many cases it must rely on the support of CNC machine tool manufacturers to solve the problem
As a result, the faulty machine tool is often not repaired in time, which prolongs the downtime of the fault and reduces the production efficiency of the CNC machine tool.
On the other hand, this also makes the technicians of some CNC system manufacturers exhausted, thus increasing the after-sales service cost of the enterprise

specific Embodiment approach

[0010] 1) CNC machine tool status monitoring and fault preprocessing terminal

[0011] The CNC machine tool state monitoring and fault preprocessing terminal mainly completes the functions of four parts, namely monitoring function, information communication function with the CNC system, status data and fault data preprocessing function, and remote communication function.

[0012] The first function is to monitor the main signals that can reflect the movement status and processing status of CNC machine tools. The monitoring objects are mostly spindles, feed axes, hydraulic and pneumatic equipment, etc. The status monitoring signals are mainly divided into power, vibration, pressure, flow and temperature etc.

[0013] Power signal monitoring is to monitor the state of the machining process by monitoring the input voltage and current parameters of the CNC machine tool. These parameters reflect the working status of the spindle motor, feed motor, transmission components, and cutti...
