The effects of electrode jump parameters on machining speed and depth were experimentally investigated in linear motor equipped electrical discharge machining. A new definition named “Machining speed break point” is introduced, theoretically calculated from a proposed electrode jump and debris exclusion model, and compared with the experimental results. Additionally, an algorithm is developed to calculate the accumulation of debris in machining gap. The algorithm showed that the debris concentration in gap rises suddenly before the machining speed break point.
