The surface fatigue layers made of Cr12 were machined by the handheld high velocity arc machining equipment, the machined surface was observed by SEM, and the material removal mechanisms was studied. The results show that the material removal mechanisms of handheld high velocity arc machining is based on lots of the pulse discharge processes, and every pulse discharge process contains five sub-processes, which is similar with the material removal mechanisms of EDM. However, the discharge gap for handheld high velocity arc machining is at the range of arc discharge gap, which is longer than that of EDM. |
