This paper presents a regression analysis of WEDM of highly porous cellular material. The purpose of the analysis is to provide an empirical model to assess the influence of the cutting conditions and the workpieceheight on the EDM speed. The research was carried out on EcoCutWEDM machine-tool by the method of full factorial experiment. Highly porous cellular material workpiece based on nichromewas selected as a sample. Empirical equation which characterizes the correlation between the EDM speed and selected factors was obtained. The resulting empirical model allowsassessing the influence of the cutting conditions and the workpiece height on the WEDM speed. The equation can be used to optimize the selection of the cutting conditions.
