The electric double layer with the transmission of particles was presented based on the principle of electrochemistry. In accordance with this theory, the cavitation catalysis removal mechanism of ultrasonic-pulse electrochemical compound machining （UPECM） based on particles was proposed. The removal mechanism was a particular focus and was thus validated by experiments. The principles and experiments of UPECM were introduced, and the removal model of the UPECM based on the principles of UPECM was established. Furthermore, the effects of the material removal rate for the main processing parameters, including the particles size, the ultrasonic vibration amplitude, the pulse voltage and the minimum machining gap between the tool and the workpiece, were also studied through UPECM. The results show that the particles promote ultrasonic-pulse electrochemical compound machining and thus act as the catalyzer of UPECM. The results also indicate that the processing speed, machining accuracy and surface quality can be improved under UPECM compound machining.
