Original abstract

Wire electrical discharge machining (WEDM) is an unconventional technology that is indispensable in almost all industries. However, due to its energy demands, the effort is to maximize the cutting speed with an emphasis on maintaining the quality of machined surfaces, which also often contain a number of defects in the form of cracks or burnt cavities. For this reason, the aim of this study was to find the optimum setting of the machine parameters using a design of experiment consisting of 33 rounds, with the material of pure molybdenum being examined. An extensive analysis of all machined samples was performed in terms of defects occurrence in the surface and subsurface layers, the analysis of topography and morphology including 3D surface reliefs, the analysis of chemical composition with dependence on diffusion processes and measurement of residual stress in the workpieces.
