304 stainless steel sheets are widely used in coal mine machinery equipment because of their excellent performance, and EDM is a reliable cutting processing with high stability and precision. The electrical parameters and wire speed have a great influence on the quality and efficiency of EDM processing. The influence of the main process parameters such as pulse width, ratio of pulse width and pulse interval, peak current and wire speed on cutting seam width, surface roughness and machining efficiency of EDM were studied by orthogonal experiment, and the mechanisms has been analyzed. The conclusion can guide the selection of the process parameters in the process of EDM.
