“…Therefore, from the mentioned preview it is clear that both the hardware and software precision of the wire lead, the process parameters and the heat load, considerably affect the final quality of the machined surface after WEDM in terms of its geometrical accuracy [17]. At the same time, the geometrical accuracy of the machined surface in combination with the mentioned WEDM parameters are also influenced by the structure [18,19] and chemical composition of the wire electrode [20]. However, because of the relatively complex problems in the given area, there is a lack of comprehensive and exact description of the influence of mechanical, physical and chemical properties of the wire electrode material and the machined material, as well as the WEDM process parameters, on the quality of the machined surface in terms of geometrical accuracy [21,22].…”

Abstract:The geometrical accuracy of the machined surface can generally be understood mainly as accuracy of shape, orientation, position and run-out. As a general rule; it is quantified by the corresponding deviations from the nominal area. The size of the geometric deviation from the nominal area may in practice affect the conventionally measured value of the dimension, even if the required dimensional tolerance is adhered to. Since electro-erosive machining technology belongs to very precise finishing technologies; even the small geometrical accuracy deviation has a negative impact on the resulting quality of machined surfaces. The aim of the experiments was to contribute to the knowledge database, which defines the influence of the process parameters at electrical discharge machining with the CuZn37 tool electrode on errors of geometrical accuracy of the machined surface. On the basis of the results of the experimental measurements, graphical dependencies were determined which predict geometrical accuracy of the machined surface in terms of the maximum deviation of flatness after electrical discharge machining of tool steel EN X30WCrV9-3 (W.-Nr. 1.2581) with CuZn37 wire electrode of 0.20 mm diameter to determine the appropriate combination of process parameters.

“…From this overview of basic operating factors it can be concluded that substantial negative impact on the geometric accuracy of the machined surface after WEDM has insufficient kinematic precision of electro-erosion machines, low precision of mechanical lead [20], management software errors of wire electrodes [21], but also an unsuitable combination of process parameter settings.

Geometrical precision machined surface is generally understood as mainly precision shape, orientation, location and run-out. As a rule, it is measuring the appropriate deviations from the nominal surface. The geometric size of this deviation from the nominal surface can in practice affect the conventionally measured value for the dimension and the dimension whilst maintaining the required tolerance. Because the WEDM technology is among the most accurate technology, the small final geometric accuracy deviation has also a negative impact on the final quality of the machined surface. The paper aimed to describe errors geometrical precision of machined surface which occurs in wire electrical discharge machining (WEDM) and quantify their scope.

At present, we cannot imagine a modern production process without computer support. At the same time, its integral part is the implementation of advanced and highly sophisticated production processes and technologies. Their aim is first and foremost to ensure quality production of products with high economic efficiency of the production process. EDM technology is one of the currently active progressive technologies. This is a technology that in practice is characterized by high product quality. The high quality of products not only through this progressive technology, but also other, whether conventional or progressive, is difficult to achieve without computer support. The aim of the paper is therefore to demonstrate the process of manufacturing a die-casting mould using progressive EDM technology using computer support.
