碩士 === 大葉大學 === 自動化工程研究所 === 89 === The purpose of this research is to utilizing the gap Control on the electric discharge of scanning process allowed the electrode to automatically compensate its system rather than calculated its compensation for each single entry. First of all, a ED-scanning process of servo control has to be in sequence. 1. Discharge Gap controller：The controller can receive the gap signals from the discharge gap monitor and generate the command of Z-axis to control the electrode along the main axis. It can compensate the electrode wear automatically and increase the eroding performance. 2. Interpolator：It can generate the commands of XY axis according to the preset feed rate and the dimension definition. 3. Position controller：According to the commands from the gap controller and the interpolator the controller can drive the electrode to the position precisely. The ED-scanning procedure will deploy stage by stage under the smallest electric particle for accumulation, such accumulation has to be in unalterable stage in order to be a standard mode hole size. Also in our research shows that, by utilizing the gap servo control method when the electrode moves horizontally, if can also be regulate to compensate the wear along Z-axis, for that it can be guarantee each level of elevation measurement standing consistent. Last of all, we have also attempted to enhance a round cone shape. The experimental result, it is very clearly that the cone shape was formed, it can be visualise and distinguish the shape was not completely formatted. Our studies demonstrate that by uilitilizaing the above control strategy, the results has reached it estimation.
