“…Many multi-criteria optimization techniques have been applied to predict the global solution [42][43][44][45][46][47]. The weighted product method (WPM) is one of the multi-criteria optimization techniques to solve the conflicted multiple response problem [48,49]. It is a very simple technique to solve machining-related problems.…”

In this research, the environment-friendly dry electrical discharge machining (EDM) process is investigated to improve the microhardness, surface finish, and white layer thickness of the machined surfaces using graphite-argon gas as a dielectric medium. The graphite powder, mixed with compressed argon gas, has been used to replace the existing dielectric medium in the EDM process. Gas pressure, discharge current, pulse width, and gap voltage were working as input parameters to reduce surface roughness and enhance the microhardness and white layer thickness. The Taguchi L16 orthogonal array is applied to the design and analysis of the experimental results. The minimum surface roughness (2.23 µm) of the HN31 steel has been attained by increasing the gas pressure up to 1.0 MPa and the minimum values of pulse width (40 µs), gap voltage (40 V), and discharge current (6 A). The maximum microhardness (501.04 HV) has been obtained at 1.2 MPa of gas pressure, 120 µs of pulse width, 60 V of gap voltage, and 18 A of discharge current. The maximum white layer thickness (16.24 µm) is achieved by the maximum values of gas pressure (1.2 MPa), pulse width (160 µs), gap voltage (70 V) and discharge current (18 A). The SEM analysis had been done to reveal the white recast layer thickness and surface roughness of the machined surfaces of the dry EDM process. The SR is increased by the recast layer, pores, and microcracks on the machined surfaces. Finally, the multi-criteria optimization technique: Weight Product Method (WPM) is applied to predict optimum process parameter settings: GP: 1.2 MPa, PW: 120 µs, GV: 50 V, and DC: 18 A to meet the best machining performances (MH=493.32 HV, WLT= 14.28 µm, and SR= 3.82 µm). The validation tests were done to confirm the predicted results obtained by both the Taguchi and WSM methods.

“…The properties of the resin matrix are shown in table 3. The resin matrix was prepared by mixing 90% epoxy resin (LY 556) and 10% hardener (HY 951) before the fabrication process [38]. The composite specimens have been fabricated using eight different natural fibers (table 4).…”

In this research, the hybrid natural fiber composite specimens were fabricated with a 64 wt.% epoxy resin matrix, 20 wt.% coir fiber, and 16 wt.% of various natural fibers by the hand-layup method. The influences of various natural fibers (Coir, Jute, Flax, Cotton, Human Hair, Sisal, Kenaf, and Calotropis) on the mechanical characteristics (tensile, flexural, and impact strengths) and drilling properties (delamination factor and ovality) of the Coir-fiber based hybrid composite have been investigated. The maximum tensile strength (48.15 MPa), maximum flexural strength (47.87 MPa), and maximum impact strength (2.85 kJ/m2) have been obtained by Coir/Flax, Coir/Sisal, and Coir/Hair Fiber hybrid composite materials, respectively. The minimum delamination factor (1.0) and ovality (169.4 µm) were obtained by coir/flax and coir/jute hybrid composite specimens when compared to other combinations of specimens. The delamination factor and ovality of the drilled hole of all combinations of hybrid composite specimens have been analyzed by scanning electron microscopy (SEM) images. The delamination factors of Coir/Flax and the drilling ovalities of Coir/Jute composite specimens are lower than those of other combinations of Coir-fiber-based composites.

“…In 2022, Boopathi et al dealt with the influence of process parameters (traverse speed and water jet pressure) and the makeup of the composite in terms of the percentage representation of its individual components on surface roughness and kerf angle using the Taguchi method. It was observed that kerf angle and surface roughness were greatly impacted by the percentage of neem wood saw powder, table traveling speed, and water-jet pressure [56].…”

The paper deals with the application of abrasive water-jet cutting to composite material containing natural reinforcement—wood plastic composite. The specimens were cut through the application of four flows of different abrasive mass: 150, 200, 250, and 300 g·min−1, respectively, and under different traverse speeds required to achieve the (expected) quality level Q1–Q5 (according to the SN 214001: 2010 standard). The output quality of Q1–Q5 was set in the CNC cutting programs and the real traverse speed values were calculated by machine control system according to change in the flow of the abrasive mass. The quality of surface topography was assessed using a tester (contact roughness) and an Inspectis digital zoom microscope. The results of topography–surface roughness parameters Ra presented here are compared with the values normalized for individual samples sets. The applied technology, i.e., the AWJ, eliminated the problem of tool wear and adhesion of the thermoplastic matrix to tool surfaces (compared to standard machining).
