文摘

A simulation and machining experiment on temperature during micro-detonation of striking arc machining (MDSAM) of silicon nitride ceramics are performed to reveal the material removal mechanism and study the effect of process parameters on machining performance. A mathematical model is developed for the temperature field of MDSAM, and the temperature and ablation cavity shape of silicon nitride ceramics are studied via simulation method and a machining test. The effects of parameters on temperature field and cavity dimension during MDSAM were computed and analyzed. The results indicated consistency between the simulation and experimental outcomes and showed that machining performance was strongly affected by the process parameters. Bigger working current, pulse width, and small working distance can yield higher temperature and machining efficiency. The nozzle radius should range from 1 to 1.4?mm. This research serves as reference for revealing the machining mechanism and presents a method for the precise control of MDSAM.
