【 摘 要 】

Micro-Electrical Discharge Machining (EDMs) is a manufacturing process in which the desired shape of the work-piece is obtained by electrical discharge. The removal of the material from the surface of the work-piece occurs by rapid current discharges occurring between two electrodes separated by dielectric medium and subjected to an electric voltage. The spark is generated between the electrodes when the voltage applied is high enough to breakdown the dielectric. As a result of this the material is removed from the surface of the work-piece. Generally, Micro-EDM operates on flat surfaces. In this paper, a controller is designed for Micro-EDM to operate on a cylindrical work-piece. The parameters to be controlled are the speed of the motors which will control the electrode and the work-piece, the spark generated and the discharge gap. A PID controller will be implemented to control the entire system. Each parameter will have its own PID controller. The controller will be designed and simulated using MATLAB/SimuLink software.
