Aiming at traditional engineering ceramics high rough machining costs and low efficiency, arc-induced electricity-detonation processing method is introduced. During Si3N4 ceramic arc-induced electrical explosion processing experiments, carry out the experimental study of the main process parameters affecting the temperature distribution. Based on brief analysis of process parameters on the temperature distribution, use the orthogonal test and regression analysis to establish the temperature field prediction model, and acquire the influence of process parameters on the temperature distribution. Simulation results show that the temperature distribution increases with the increase of the processing of current and pulse width and decreases with the increase of the distance between the nozzle and the work piece and increase of nozzle radius. The results may give a reference basis for process control of the arc induced electrical explosion, and for processing work pieces of various shapes in future.
