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.

Disclosed is an automatic hole-processing method with self-adapting adjustment of processing parameters, including the following steps: performing tool feeding, detecting whether the rotate speed changes or not, if changes, judging the type of the processing material according to the new rotate speed after stabilization (if not, the tool feeding is continued); feeding the tool according to the processing parameters suitable for the material, detecting whether the rotate speed changes or not, if changes, judging whether the hole processing has been completed or not according to the new rotate speed after stabilization (if not, the tool feeding is continued), if completed, retracting the tool with the set parameters (if not, judging the type of the processing material according to the new rotate speed after stabilization, and repeating the above steps), completing the hole processing. During the hole processing in the present disclosure, there is no need to know the type of workpiece material of each processing hole in advance and to set processing parameters for each material respectively; there is no need for axial tool setting, processing parameters can be changed automatically after the tool contacts the workpiece; there is no need to know the total thickness of each processing hole material in advance and to set the feed stokes respectively, after cutting through the workpiece, the tool automatically identifies and begins to retract.

A method for controlling a device system is disclosed, and the device system includes a tool device and a motorized advancing apparatus during the machining of a workpiece composed of a first material and a second material different from the first material. The method includes machining the workpiece by the device system initially in a first operating mode with first machining parameters that are stored for the first material. After the start of the machining of the workpiece in the first operating mode, the method includes measuring and storing a first machining progress of the tool device as a reference value. During the machining of the workpiece in the first operating mode, the method also includes regularly measuring and comparing with a first threshold value a current machining progress of the tool device.
