摘要：

A single-pulse experiment was conducted to study the mechanism of electrical discharge machining (EDM) ablation. An equivalent model of EDM ablation was established to explain the changes in the oxide layer of electrodes. Theoretical analysis was performed to understand the machining mechanism behind EDM ablation. Four stages and three models of EDM ablation were proposed to explain the machining mechanism of this process. Tests were performed to compare normal EDM, EDM spark-induced combustion, and EDM spark-induced explosion. The processing depth and surface morphology of the machined workpiece in the experimental results are coincident with those in the theoretical analysis results.
