“…The artificial neural network was utilized to establish a mathematical relationship between the cutting parameters and output measures [18,19]. It can be seen from above that the MRR and Ra are the most widely characteristics that are used to describe WEDM cutting conditions [6][7][8][9][10][11][12][13][15][16][17][18].

In this paper, the effects and the optimization of cutting parameters on surface roughness (Ra) and material removal rate (MRR) in the wire electrical discharge machining (WEDM) of high hardness tool steel YG15 are analyzed. In the WEDM process, the key process parameters, such as pulse-on time, pulse-off time, power, cutting feed rate, wire tension, wire speed, and water pressure, are optimized. Experimental data were initially collected based on the Taguchi method of experimental design, which are L 18 2 1 × 3 5 and L 18 2 1 × 3 4 Taguchi standard orthogonal array on rough and finish cutting experiments, respectively. The level of importance of the cutting parameters on the Ra and MRR was determined on both finish and rough cutting by using statistical analyses; average gap voltage is discussed in order to balance cutting efficiency and stability on both finish and rough cutting. In addition, comparative analysis of finish and rough cutting is drawn to analyze the difference between rough cutting and finish cutting. Then, regression models and signal-to-noise ratio are used to obtain the optimum cutting parameter combination. Finally, the results present the optimized MRR and Ra of the rough and finish process, respectively, and confirm the efficiency and abilities of the model.

“…These investigations show that the surface roughness of the process is closely dependent on the machining parameters. In Gokler and Ozanozgu (2000), the experimental study aims to select the most suitable cutting and offset parameter combination for the WEDM process in order to get the desired surface roughness value for the machined workpieces. A series of experiments have been performed on 1,040 steel material of thicknesses 30, 60, and 80 mm, and on 2,379 and 2,738 steel materials of thicknesses 30 and 60 mm.…”

Wire electrical discharge machining has become an important nontraditional machining process, as it provides an effective solution for producing components made of difficult-to-machine materials such as titanium, zirconium and intricate shapes, which are not possible by conventional machining methods. Due to large number of process parameters and responses, lots of researchers have attempted to optimize the process parameters. This paper reviews the advances in research of WEDM on relation between different process parameters, include pulse-on time, pulse-off time, servo voltage, peak current, dielectric flow rate, wire speed, wire tension on different process responses include material removal rate (MRR), cutting speed (Vc), surface roughness (Ra), and wire wear ratio (WWR) of the wire electrode. Effect of composition of material on the manufacturability of wire EDM has also been reviewed. And at last, wire failure analysis is discussed.

Investigations of the effects of machining parameters on the cutting quality of wire-electrical-discharge-machining (WEDM) cutting of an annealed Inconel 718 nickel-based superalloy are described in this paper. The cutting-quality characteristics considered are the kerf width, the recast-layer thickness and the surface roughness of the cut specimens. The essential process input parameters were identified as the pulse-on time, the pulse-peak current, and the injection pressure. The analysis of variance (ANOVA) technique was used to find the parameters affecting the cut quality. The regression analysis was used for the development of empirical models able to describe the effects of the process parameters on the quality of the WEDM cutting. The ANOVA results show that the pulse-on time and the pulse-peak current are significant variables affecting the surface roughness of wire-EDMed Inconel 718. The surface roughness, the kerf width and the recast layer of the test specimens increased as these two variables increased. The measured and modelled results were in good agreement with respect to the correlation coefficients Ra, RLT and Kü. Keywords: wire-electrical-discharge machining (WEDM), Inconel 718, recast layer, surface morphology, analysis of variance V~lanku je opisana raziskava vplivov parametrov obdelave na kvaliteto reza, z`i~no elektroerozijo (WEDM) rezane`arjene nikljeve superzlitine Inconel 718. Upo{tevane so bile karakteristike reza, kot je {irina reza, debelina nataljenega sloja in hrapavost povr{ine odrezanega vzorca. Ugotovljeno je, da so bistveni vhodni parametri procesa impulzi v~asu, tok vrha impulza in tlak vbrizgavanja. Za iskanje parametrov, ki vplivajo na kvaliteto reza je bila uporabljena tehnika analiza variance (ANOVA). Regresijska analiza je bila uporabljena za razvoj empiri~nega modela, ki lahko opi{e vpliv procesnih parametrov na kvaliteto WEDM rezanja. Rezultati iz ANOVE ka`ejo, da sta impulz v~asu in tok vrha impulza pomembni spremenljivki pri rezanju Inconela 718 z`i~no elektroerozijo. Hrapavost povr{ine, {irina zareze in debelina pretaljene plasti so nara{~ali pri preizkusnih vzorcih,~e sta nara{~ali ti dve spremenljivki. Izmerjeni in modelirani rezultati so se dobro ujemali s korelacijskimi koeficienti Ra, RLT in Kü.
