The paper deals with the assessment of significance impact of selected technological parameters in Wire Electrical Discharge Machining on final quality of machined surface in terms of surface roughness. For determining the significance of impact of the individual technological parameters was used the statistical method Design of Experiments which is conventionally used for mathematical modelling the impact of selected technological parameters on quality indicators of machined surface previously untested experimental samples. The aim of the paper was, based on experimentally-made samples of alloyed steel MaragingSteel MS1 by WEDM technology, to select the technological parameters which significantly affect machined surface quality in terms of surface roughness parameter Rz.Here you should describe the paper idea in short.
