Originální abstrakt

Wire electrical discharge machining(WEDM) represents an effective technology of unconventional machining used for the manufacture of components having complex shapes, for machining of hard materials after heat treatment or of non-ferrous metals that are difficult to machine with conventional processes. One the non-ferrous materials is also pure aluminium 99.5 used for this experiment that consisted of the use of design of experiments for machine parameters setup and the fabrication of 33 samples. The objective of this study was to find key parameters of machine setup for the manufacture of high-precision components with required surface quality. For this purpose, an analysis of the morphology of the surface layer was made using electron microscopy (SEM), including a local analysis of the chemical composition (EDX). In addition, the surface topography using 3D profilometer and profile and area parameters of the surface quality were evaluated, including 3D colour filtered and unfiltered images of surfaces taken using light microscopy. The prepared metallographic preparations allowed to make an analysis of the sub-surface area, including a local chemical microanalysis of “recast layer” using EDX.
