  • Monitoring method for vibration drilling state of stack structure material
    Patent number: 12189358
    Abstract: A state monitoring method for vibration drilling of a stack structure material is provided. A load power and a torque value of a drilling spindle is monitored during machining. Drilling state are divided according to a machining material of a drill. According to a data of a test library, reference thresholds of two monitoring objects for judging the change of the drilling state are set to achieve the state monitoring for the drilling process. The method monitors the machining process through the monitoring module in the machining system.
