Original abstract

Wire electrical discharge machining (WEDM) is a non-conventional machining technology which uses electrical impulses between two electrodes to cut materials. The long-term trend of increasing accuracy and surface finish quality leads to the necessity of its detailed examination. The study deals with the evaluation of the surface morphology by electron microscopy (SEM) and chemical composition analysis (EDX). Object of interest was to assess the amount of adhering material from brass wire electrodes. Furthermore, it also examined surface and profile parameters of the machined surface. Samples for the experiment were made of X210Cr12, tool alloy steel for cold working, which was subject to 4 different types of heat treatment. Dependence between the amount of adherent material from the wire electrode and the the of machined material has been found.

Elektroerozivní drátové řezání (WEDM) je nekonvenční technologie obrábění, která využívá k dělení materiálu elektrických impulzů mezi dvěma elektrodami. Dlouhodobý trend zvyšování přesnosti a kvality obrobeného povrchu vede k nutnosti jeho podrobného zkoumání. Studie se zabývá vyhodnocením morfologie povrchu pomocí elektronové mikroskopie (SEM) a analýzou chemického složení (EDX). Objektem zájmu bylo posouzení množství ulpělého materiálu z mosazné drátové elektrody. Dále byly zkoumány plošné a profilové parametry obrobeného povrchu. Vzorky pro experiment byly vyrobeny z nástrojové legované oceli pro práci za studena X210Cr12, která byla zpracována 4mi různými druhy tepelného zpracování. Byla nalezena závislost mezi množstvím ulpělého materiálu z drátové elektrody a tvrdostí obráběného materiálu.
