Original abstract
Wire electrical discharge machining (WEDM) is an unconventional technology of machining that applies physical principles for material removal. To ensure efficient machining, it is appropriate to have the cutting speed as high as possible; however, the quality of the surface to be machined shall also be taken into account. Since the cutting speed cannot be directly set on the machine, but depends on the setting of individual machine parameters, an experiment was designed to find optimum values of individual parameters to maximise the cutting speed. The examined parameters included: gap voltage, pulse on time, pulse off time, wire speed and discharge current. In addition, the study dealt with the evaluation of morphology and quality of the surfaces of machined samples manufactured at the highest and the lowest speed using a contactless profilometer based on the principle of coherence correlation interferometry.

Elektroerozivní drátové řezání (WEDM) je nekonvenční technologie obrábění, která k úběru materiálu využívá fyzikálních principů. Pro efektivní obrábění je vhodné, aby cutting speed byla co možná nejvyšší, avšak je nezbytné přihlédnout i k jakosti obrobeného povrchu. Vhledem k faktu, že cutting speed nelze na stroji nastavit přímo ale je tvořena nastavením jednotlivých parametrů stroje, byl sestaven plánovaný experiment určený k nalezení optimálních hodnot jednotlivých parametrů pro maximalizaci cutting speed. Zkoumanými parametry byly gap voltage, pulse on time, pulse off time, wire speed and discharge current. Studie se dále zabývala vyhodnocením morfologie a jakosti obrobených povrchů vzorků vyrobených nejvyšší a nejnižší rychlostí pomocí bezkontaktního profilometru založeného na principu koherenční korelační interferometrie.
