Abstract

Micro-mechanisms are one of the main areas of development in manufacturing technology widely used in various production fields. Currently, new microelements are made of superalloys due to the high requirements of corrosion resistance and temperature resistance. Furthermore, effective methods of making micro elements are sought, which on the one hand will ensure the appropriate dimensional and shape accuracy and, on the other hand, the expected surface quality. Conducted research was focused on analyzing the influence of micro wire electrical discharge machining on the parameters of selected surface topography features, which directly impact the tribological properties of the surface of micro parts. The effect of the WEDM parameters on the functional parameters of the surface texture: Sk - the roughness of the core, Spk - the roughness of the peak, Svk - the roughness of the valleys are presented and discussed.

Keywords: EDM, electrical discharge machining, holes, geometry accuracy
