Original abstract

The unconventional Wire Electrical Discharge Machining (WEDM) technology represents a vital manufacturing technology in different industrial branches, such as aviation, military, automotive or energy industry. The WEDM energy demand is considerable and it is, therefore, desirable to reduce the machining time by optimising the machining parameters. In the study, the chosen parameters were Pulse off time, Gap voltage, Discharge current, Pulse on time, and Wire feed. Another factor we investigated in our Box-Behnken design of experiment was the workpiece thickness. The cutting speed, topography, and surface morphology were analysed in the samples produced for the design of experiment. This investigation was carried out using electron microscopy. The chemical composition of individual spots was analysed as well. The samples were found not to have significant differences in the appearance of craters on the edge and in the centre. Similarly, there was no significant difference observed between thicknesses and different parameter settings. The surfaces also show a large number of small bubbles. There were, however, no cracks or other defects found, even in the cross-sections of all samples.

Elektroerozivní drátové řezání (WEDM) představuje nepostradatelnou nekonvenční technologií obrábění v mnoha průmyslech, jako je letecký, armádní, automobilní či energetický. Vzhledem k energetické náročnosti WEDM je efektivní zkrátit strojní čas na základě optimalizace parametrů nastavení stroje, kterými byly Pulse off time, Gap voltage, Discharge current, Pulse on time, Wire feed. Dalším zkoumaným faktorem vstupujícího do provedeného Box-Behnken plánovaného experimentu byla tloušťka obrobku. U vzorků vyrobených z plánovaného experimentu byla analyzována rychlost řezání, topografie a také morfologie povrchů. Toto zkoumání bylo provedeno pomocí elektronové mikroskopie, přičemž dále byla také provedena analýza chemického složení v jednotlivých místech. Bylo zjištěno, že vzorky nemají výrazné rozdíly ve vzhledu kráterů na okraji a ve středu a taktéž není významný rozdíl mezi tloušťkami a odlišným nastavením parametrů. Povrchy také obsahují množství drobných bublinek, přičemž žádné trhliny ani jiné defekty zde nebyly nalezeny a to ani v příčných řezech všemi vzorky.
