In order to explore characteristics of electrical discharge machining (EDM) SiC/Al functionally graded materials, the simulation model of EDM continuous multi-pulse discharge temperature field was established. The dynamic simulation of continuous multi-pulse discharge was carried out. The pit position of the random distribution was analyzed using life and death method. The influence of peak current and pulse width on discharge pits and material removal rate was studied and verified experimentally. The results show that with the increasing of peak current and pulse width, the material removal rate is gradually increased. The simulation results are the same direction as the experimental results, and the error analysis is carried out. The maximum error of theoretical experimental results is 9.84% and the minimum error is 5.10%.
