Original abstract
The stressed parts of forming tools are usually made of tool alloy steel X210Cr12 with additional thermal treatment. When machining these parts, due to the high demands on shape and precision, wire electrical discharge machining (WEDM) is used, which a method is belonging to the group of non-convention machining technologies. WEDM uses physical principles to cut material, which enables for machining parts which were already thermally treated. The long-term trend of improving precision and quality of the machined surface leads to the necessity of its thorough studying. This study concerns itself with evaluating the morphology of the worked surface using electron microscopy (SEM) and chemical composition analysis (EDX). The focus was to evaluate the quantity of the adhered material from the brass wire electrode. Furthermore, surface and profile parameters of the machined surface were studied using Atomic force microscope (AFM). Samples for the experiment were made of X210Cr12 steel, which was treated with 4 different thermal treatments.

Namáhané části střižných nástrojů jsou obvykle vyrobeny z nástrojové legované oceli X210Cr12 s dodatečným tepelným zpracováním. Pro obrábění těchto součástí bývá z důvodu tvarové náročnosti a přesnosti užíváno elektroerozivní drátové řezání (WEDM), které patří do skupiny nekonvenčních technologií obrábění. WEDM užívá fyzikálních principů dělení materiálu, což umožňuje obrábět již tepelně zpracované polotovary. 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 a detailní morfologie povrchu s využitím Atomic force microscope (AFM). Vzorky pro experiment byly vyrobeny z oceli X210Cr12, která byla zpracována 4mi různými druhy tepelného zpracování.
