Electrical discharge machining (EDM) is a modern technology off processing difficult to machine materials. In EDM process material is removed from the workpiece by series of electrical discharges. The final state of the surface layer directly influences the durability of the produced elements. Response surface methodology was used to build mathematical models to predict the influence of the investigated EDM process parameters on the surface layer properties. The experimental studies allowed a better understanding of the relationship between the changes of the high thermal conductivity tool steel (HTCS) surface layer properties and EDM process parameters. Developed models can be used in the EDM process as a guideline for the selection of parameters to achieve the desired surface layer properties in industrial applications. View this paper
