Study on Dry Electrical Discharge Machining

In the paper are presented results of simulation and mathematical modelling of the material removal rate of electrodischarge milling process with compressed air as dielectric. There are also presented basic characteristic of the DEDM milling process and comparison of this green machining method with kerosene based EDM milling. Presented results refer to the experiments of micro machining with thick walled electrodes. There are described advantages and drawbacks of this machining method, especially in the field of micro-machining.
