Wherein the database 20 is communicatively connected to the electronic device 10 and the discharge parameter detection device 30, respectively, and the electronic device 10 is connected to the numerical control device 40. The database 20 is used to store the discharge parameters of the tool electrodes; the discharge parameter detection device 30 is used for measuring the discharge parameter of the tool electrode, and storing the measured discharge parameter in the database 20; the electronic device 10 is configured to, in response to processing a workpiece with a tool electrode, recall, from the database 20, a discharge parameter of the tool electrode according to the profile information of the tool electrode, generate a discharge program based on the discharge parameter of the tool electrode, and send the discharge program to the numerical control device 40; the numerical control device 40 is used for receiving the electric discharge program and processing the workpiece to be processed according to the electric discharge program.
In this implementation manner, by measuring the discharge parameter of the tool electrode in advance, the discharge parameter of the tool electrode is stored in the database 20, when the center point measurement is performed on the tool electrode, the discharge parameter of the tool electrode is obtained, according to the discharge parameter, the center point measurement is performed on the tool electrode, and the measured second eccentric value is stored in the database 20, so that when the tool electrode is used, the eccentric value of the tool electrode can be directly called from the database 20, and when the tool electrode is used, the discharge parameter stored in the database 20 can be directly called without performing the center point measurement, and further the automatic machining process after the tool electrode is cut is realized.

The electrode tip detection value indicates a discharge position of the electrode tip of the tool electrode. The electrode tip detection value comprises parameter values such as the distance between the tool electrode and the workpiece, the shape and the size of the tool electrode and the like. After the central point measuring module measures the electrode tip detection value of the tool electrode, the electrode tip detection value and the file information of the tool electrode are associated and stored in the database 20.
The electronic device 10 may be any device having a man-machine interaction function. For example, the electronic device 10 may be a computer, tablet computer, mobile phone, etc. In some embodiments, the electronic device 10 may also display a system information input interface of the numerical control device 40, which is used to display a control system interface of the numerical control device 40. In some embodiments, the system interface is used to display profile information, eccentricity values, etc. of the tool electrode.
