Straka, L., & Dittrich, G. (2019). Impact of physical properties of workpiece material on material removal rate at EDM. International Journal of Engineering and Management Sciences, 4(1), 230-237. https://doi.org/10.21791/IJEMS.2019.1.29.

The volume stock removal from the workpiece during the EDM is one of the important parameters that characterize the productivity of the electro-erosion process itself. Therefore, in terms of the economic efficiency of the electro-erosion process, it is appropriate that the value of the MRR parameter is as high as possible. The paper describes the results of experimental research to identify the extent of influence of the physical properties of the workpiece material on the workpiece material removal rate at EDM. The experiments were carried out using an Aggregron Hyperspark 3 electro-erosion machine on selected tool steels. As a tool electrode material for experimental purposes, graphite with the designation EX-60 was chosen because of its practical advantages.
