A new method for controlling the electrode setback (JUMP) in EDM is presented in this paper. The static characteristics of JUMP are established experimentally and show that there is a safe range for the JUMP condition. By using self-tuning adaptive control theory, the JUMP parameters can be controlled so that the machine functions in the safe range automatically. The effectiveness of this system was confirmed by experimentation.
