“…In one study, the authors evaluated the optimized conditions of formability for the FSW of dissimilar materials of AA6061 and AA2017 using simulation and the experimental environment. The study observed a tool rotation of 1300 rpm, a traverse speed of 20 mm/min, and a tool tilt angle of 1 • were the optimized conditions for joining dissimilar materials through FSW in comparison with any other conditions tested in the study [122]. A similar study was performed on the evaluation of the curvature radius of the tool on weld performance.…”

“…It works on the tenet that, in terms of Euclidean distance, the chosen option should be the one that is closest to the positive ideal solution (PIS) and the farthest from the negative ideal solution (NIS). This method, which ranks the options according to how close they are to the ideal answer, is simple to use and efficient for handling MCDM problems [20][21][22][23].…”

“…Instead of being one piece, the D2 steelwork material is divided into 10 mm thick cubes for this study. Each wire with a 0.25 mm diameter had its input parameters changed, and the Taguchi L27 orthogonal array shown in table 2(b) was used [18][19][20][21][22].…”

“…These tables clearly demonstrate that, in the case of coated wire electrodes, pulse on time stands out as the most crucial factor, closely followed by pulse off time. Conversely, for brass wire electrodes, pulse off time takes precedence as the most significant factor, with pulse on time following closely in importance in relation to the output responses [18][19][20][21][22][23][24].…”

Metals that are electrically conductive but are difficult to work with are typically machined using WEDM (Wire Electric Discharge Machining). The production of tiny components, which are challenging to mill using earlier non-traditional machining techniques, has undergone a substantial transformation thanks to these machines. Two wire electrodes coated copper wire and annealed copper wire electrodes are used for the testing in this investigation, and the analysis is completed utilizing the tool material. The workpiece material, D2 Steel, was cut into cubes that were 10 mm thick for the experiment, and a wire electrode with a diameter of 0.25 mm was used. Using an L27 orthogonal array, six input variables were employed at three different levels in the testing. The TOPSIS technique is utilized to optimize the output variables, leading to the determination of various output parameters, including Material removal rate (MRR), Kerf width (KW), tool wear rate (TWR), and surface roughness (SR). The chosen input variables include wire tension (WT), a gap voltage (GV), input current (IP), wire feed rate (WF), pulse off time (Toff), and pulse on time (Ton). The 10 mm-wide D2 steel was milled using two wire electrodes, and an ANOVA table was made to identify the factors that had the greatest impact on the WEDM parameters. The rank and ideal Wire EDM parameter values must be calculated using main effect plots and tables of replies. From this investigation, we can also draw the conclusion that for machining D2 steel, annealed wire electrodes provide greater MRR than coated wire.

This work focuses on optimizing process parameters in underwater friction stir welding to study their impact on the mechanical characteristics of aluminum 2014 T6 and 6082 T6 joints. The aluminum plates are precisely machined to provide the necessary polish for the underwater friction stir welding process (UFSW). Experiments are designed using Taguchi L-9 orthogonal array, considering three process parameters: speed, transverse speed, and tool angles at three levels each. The aluminum plates of series 2014-T6 and 6082-T6 are securely installed in the machine. The plates will be welded using the UFSW process using a taper pin tool. The welded plates are next subjected to tests to assess their mechanical qualities. Tests for tensile strength, hardness, and impact strength are conducted on the welded area of the plate to determine its mechanical qualities. An ANOVA was conducted to determine the significant influence of each variable. The optimal values achieved are Tensile Strength of 185.592 N/mm2, Hardness of 75.1 (BHN), and Impact Strength of 21.236 Joules at a speed of 1120 rpm, transverse speed of 80 mm/min, and tilt angle of 2 degrees.
