Influence of Carbon-Protection-Film to Deterioration of Electrode in EDM
In this paper, process of how carbon-protection-film is formed and dynamic influence process of carbon-protection-film to electrode erosion are discussed in limited continuous pulse discharge. It is considered that the compensation of carbon-protection-film to anode erosion results in the cathode erosion bigger than that of the anode under long time EDM.
