Original abstract
Wire electrical discharge machining (WEDM) is an unconventional machining technology which is widely used in all industries. Due to the increased energy demand of WEDM, there is an effort to reduce machining times and thus maximise the material removal rate (MRR). Thus, this study aimed to perform the design of experiment to study the effect of WEDM machining parameters on the resulting MRR, topography, morphology, and subsurface condition of the produced samples. The materials investigated included titanium alloy Ti-6Al-4V, aluminium alloy 7475-T7351, nickel alloy Nimonic C 263, wear-resistant Hadfield steel, copper alloy Ampcoloy 35, pure molybdenum 99.99, and high-entropy alloy FeCoCrMnNi. The highest MRR values were achieved for 7475-T7351. Nimonic, Hadfield steel, Ampcoloy, and molybdenum materials reached similar MRR values and the lowest MRR values were studied for Ti-6Al-4V and FeCoCrMnNi materials. Cracks were visible on all samples of Ti-6Al-4V, molybdenum and aluminium alloy 7475-T7351, while burnt cavities were found in Hadfield steel.

Elektroerozivní drátové řezání (WEDM) je nekonvenční technologie obrábění, která je široce používána ve všech průmyslových odvětvích. Vzhledem ke zvýšené energetické náročnosti WEDM je snaha zkrátit obráběcí časy a tím maximalizovat rychlost úběru materiálu (MRR). Cílem této studie bylo provést návrh experimentu pro studium vlivu parametrů obrábění WEDM na výslednou MRR, topografii, morfologii a podpovrchový stav vyrobených vzorků. Zkoumané materiály zahrnovaly titanovou slitinu Ti-6Al-4V, hliníkovou slitinu 7475-T7351, niklovou slitinu Nimonic C 263, otěruvzdornou ocel Hadfield, slitinu mědi Ampcoloy 35, čistý molybden 99,99 a vysoce entropickou slitinu FeCoCrMnNi. Nejvyšší hodnoty MRR byly dosaženy u 7475-T7351. Materiály Nimonic, Hadfield steel, Amcoloy a molybden dosáhly podobných hodnot MRR a nejnižší hodnoty MRR byly studovány pro materiály Ti-6Al-4V a FeCoCrMnNi. Na všech vzorcích Ti-6Al-4V, molybdenu a hliníkové slitiny 7475-T7351 byly viditelné trhliny, zatímco vypálené dutiny byly nalezeny v Hadfieldově oceli.
