Patent ID: 8560110

Claim:
An electroerosion control system, comprising: a general Computerized Numerical Controller (CNC) controller being configured for controlling a general CNC machine process, wherein the general CNC controller includes an Numerically-Controlled (NC) kernel and a Programmable Logic Control (PLC), the NC kernel stores a NC part program and the PLC stores a ladder program; a power supply for energizing a tool electrode and a workpiece to be machined, wherein the power supply includes a voltage measurement circuit for sensing real-time voltage of a working gap; an electroerosion controller electrically connecting with the power supply for controlling an output of the power supply, and adaptively and electrically connecting with the general CNC controller for communication thereof, wherein the electroerosion controller performing electroerosion control according the real-time voltage of the working gap; and a sensor sensing real-time status information of the working gap between the tool electrode and the workpiece and for sending the real-time status information to the electroerosion controller, the electroerosion controller automatically controlling the electroerosion machining process through the general CNC controller according to the real-time status information of the working gap, wherein the general CNC controller includes a Tool Retraction and Recovery (TRR) motion and the electroerosion controller sends jump up/down signal according to the real-time status information of the working gap to the general CNC controller to trigger the TRR motion, wherein a jump distance of the jump up/down action is written either in the NC part program or a parameters table of the NC kernel; and wherein the electroerosion controller sends a jump up/down signal to the PLC of the general CNC controller, the PLC transmitting the jump up/down signal to the NC kernel where the NC part program is stored.
