Original abstract

The objective of this work is to assess cutting speed during the wire electrical discharge machining (WEDM) depending on the machine parameters setting (gap voltage, pulse on time, pulse off time, wire speed and discharge current) and follow-up assessment of the surface quality achieved. In order to achieve efficient machining the maximum cutting speed is required, however maintaining of the required quality and functional characteristics of the machined surface must be considered. Surface morphology during the wire electrical discharge machining is formed by a high number of craters, of which depth has direct effect on area parameters and profile parameters of the surface quality. These parameters were evaluated using Contactless 3D profile-meter based on the principle of coherence correlation inter-ferometry IFM G4 from the Alicona producer.

Czech abstract

Cílem tohoto článku je vyhodnotit cutting speed při elektroerozivním drátovém řezání (WEDM) v závislostech na nastavení parametrů stroje (gap voltage, pulse on time, pulse off time, wire speed and discharge current) a následném vyhodnocení dosažené jakosti povrchu. Pro efektivní obrábění je nezbytné dosažení co nejvyšší cutting speed avšak s přihlédnutím k zachování požadované kvality a funkčních charakteristik obrobené plochy. Při elektroerozivním obrábění je morfologie povrchu tvořena velkým množstvím kráterů, jejichž hloubka přímo ovlivňuje plošné i profilové parametry jakosti povrchu.
