| Popis: | 100 The spark of Electrical discharge machining(EDM) can locally produce high temperature, which is able to erode any conductive material. Currently used EDM transfers limited energy into the gap of discharging to avoid abnormal discharging. A corona ignited capacitive discharging(CICD) method is proposed in this thesis, the method can prevent the limitation of gap energy. To study the efficiency of CICD single pulse discharging is and a testing platform is designed and manufactured in this thesis. The platform is consisted of mechanism and controller. The controller is implemented by TMS F2808 eZdsp emulation board, control code is produced via Real-Time Workshop of MATLAB, transferred from designed SIMULINK model which is designed to progress the single pulse discharging of CICD by controlling a servo motor to move electrodes. In this thesis, single pulse discharges of CICD are applied to SKD11 with different gap distance. By inspecting the eroded spot to evaluate the correlation between the efficient of CICD and discharging distance. It is found the platform and the evaluation of single pulsed CICD in this thesis will be a good reference for the innovative CICD discharging method. |
