Numerical Simulation of Temperature for Si3N4 Ceramics during Micro-detonation of Striking Arc Machining
Micro-detonation of striking arc machining (MDSAM) is a newly developed special machining technology for engineering ceramics. In the machining process, the high temperature of micro-detonation makes ceramics surface material melt or decompose. The material is removed and a round cavity is formed. Since the research on this technology has just begun, there are part of the mechanism is not fully clear. Therefore, the simulation of the machining process is of important significance. In this paper, a theoretical model of temperature for Si3N4 ceramics during MDSAM is established and the temperature is simulated based on finite element method. By means of machining experiment, the material removal mechanism of Si3N4 ceramics and the validity of simulation results are studied. The simulation results provide important theoretical support to reveal the machining mechanism of MDSAM.
