Investigation on Pulse Electrochemical Machining Characteristics of Lamellar Cast Iron using a Response Surface Methodology-Based Approach

In this contribution, the potential of Pulse Electrochemical Machining (PECM) for the machining of lamellar cast iron is investigated with regard to the machining performance during electrolysis with sodium nitrate as electrolyte and stainless steel as cathode. Therefore, the material removal characteristics of lamellar cast iron with PECM are determined by performing systematic design of experiments techniques applying an industrial PECM machine system (PEMCenter8000) to fulfill the effective utilization of the process and to minimize the number of trials. An analysis of the precision of the manufactured geometries and the possibility of generating defined surface qualities are contents of this study.
