“…The Taguchi method is a pragmatic solution for enhancing the product performance, design, or process while keeping a close eye on cost and time [22,23]. This technique has been used to successfully optimize a variety of processes in numerous researches [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40]. With the help of the Taguchi's orthogonal array (OA) concept, which provides somewhat reduced variations or inconsistency for such experimentations including an optimized variety of design factors which influence the process.…”

In the current work, the statistical analysis of various electric discharge machining parameters on Al6082 ultra‐fine grained aluminium alloy using Taguchi method has been presented. Repetitive corrugation and straightening (RCS) method was employed to obtain ultra‐fine grained aluminium alloy. The electric discharge machining studies were carried out for test variables – pulse off time, pulse on time and current (I). The specimens were machined in dielectric medium with current range of 3 A to 9 A in step of 3 A. Machining features of the samples analysed statistically by adopting the Taguchi's ‐ design of experiments (DOE) methodology. Impact of parameters on material removal rate (MRR) and surface roughness (SR) were examined via signal‐to‐noise ratio (S/N ratio, expressed in decibel, dB) as well as analysis‐of‐variance (ANOVA). Outcomes disclose that every selected response explicitly surface roughness (SR) and material removal rate was significantly influenced by parameters. The material removal rate was found to rise with discharge current and decrease with the duration of pulse on time and the duration of pulse off time. On the other hand, the surface roughness increased with increase in peak current and decreased with pulse on time and pulse off time especially. The machining mechanisms were examined by scanning electron microscopy.

“…Statistical experimental design methods can solve these difficulties mentioned above systematically and efficiently. Taguchi method, a well‐known statistical method, has been originally employed to improve the quality of products by the application of statistical and engineering concepts . This method has become a powerful tool for minimizing the number of experiments and then optimizing the process parameters.…”

The hot deformation behavior of AISI 316LN austenitic stainless steel was studied through isothermal hot deformation tests conducted on Gleeble 1500 thermo-simulation machine. By using Taguchi method with an L16 (4 3 ) orthogonal array, the hot deformation conditions including deformation temperature, strain rate and strain were optimized for obtaining minimum mean grain size of the steel. Analysis of variance was used for determining the effect of the hot deformation parameters on the mean grain size. The results suggested that the strain had the most significant effect on the mean grain size among the three factors. The percent contributions of deformation temperature, strain rate and strain to the mean grain size were 0.80 %, 2.45 % and 93.32 %, respectively. Finally, the confirmation experiment under the optimum conditions, i.e., 1050°C temperature, 0.01 s -1 strain rate and 0.7 strain was carried out. The observational mean grain size (11.4 μm) is approximately twelve times smaller than that of the initial microstructure.Keywords: 316LN / austenitic stainless steel / gleeble / hot deformation / taguchi method / grain size Schlüsselwörter: X2CrNiMoN17-11-2 / austenitischer Stahl / Gleeble / Warmumformung / Taguchi Methode / Korngröße

“…Taguchi approach was used as an optimization process because it reduces the number of experiments producing high-quality weld with less cost [8]. The analysis of variance (ANOVA) was introduced to find the significant outcome of input welding parameters upon output response [9].…”

Friction stir welding (FSW) is a solid-state welding technique in which the joint quality was predominantly subjected to heat formation throughout the metal welding process. The weld joint produced from FSW was better than the other fusion welding process. In this research, the base plates AA6101 and C11000 of 5 mm thickness were joined using the hardened oil-hardened nonshrinkable steel(OHNS) tool by the FSW method. The design of experiment (DOE) was used to optimize the input parameters such as tool rotational speed (rpm), feed rate (mm/min), and tool pin offset (mm) on output parameter ultimate tensile strength (UTS). The design of experiment (DOE) was carried out by employing a Taguchi L9 orthogonal array, three factors, and three levels for obtaining a quality joint with good strength. The results of nine trial runs from the Taguchi experimental approach were formulated and analyzed using the statistical tool analysis of variance (ANOVA) using MINITAB 19 software. ANOVA analysis was employed to find the contribution of the input parameters toward the output. The optimized input process parameters will help to create effective weld joints. This study revealed that tool pin offset towards softer metal at medium tool rotational speed would create joints with the highest UTS. Scanning Electron Microscope (SEM) was applied to investigate the structural changes in the FSW of Al-Cu joints.Friction stir welding (FSW) is a solid-state welding technique in which the joint quality was predominantly subjected to heat formation throughout the metal welding process.
