WebJan 22, 2024 · However, too much electrolyte flow can remove metal beyond the area targeted for grinding. Feed Rate — As with low vs. high voltage, the rate of material feed has an impact on the electrochemical and abrasive actions. In this case, a slower feed results in more electrochemical action and less abrasive force, while a faster feed … http://www.minaprem.com/machining/principle/parameter/what-is-feed-rate-in-machining-its-unit-value-effects-and-selection/#:~:text=Feed%20rate%20in%20drilling%E2%80%94Must%20be%20very%20low%20otherwise,in%20knurling%20but%20feed%20rate%20is%20very%20high%29.
