Electrodischarge machining (EDM) in the gas can be an alternative to traditional electrodischarge machining in dielectric liquids. Dry EDM has many advantages comparing with traditional EDM, what is more with optimal machining parameters it is possible to gain very good accuracy and quality of machined surface. Moreover, EDM in the gas is environmental friendly, even that it is still not used in industry because of the problems with proper heat dissipation from the machining gap which results in problems with achieving satisfying repetitiveness. In the paper the results of austenitic steel X5CrNi 1810 electrodischarge drilling in the air and in the air in deionised water environment were presented. The aim of the research was to determinate the influence of current intensity, current voltage, pulse on time, pulse off time and a type of electrodes’ polarization on the material removal rate, working electrode wear and the machined material surface structure.
