The cutting fluid’s lubrication affects a workpiece’s surface finish and cutting tool lifespan during turning. To optimize machine performance, appropriate lubrication is needed. Empirical experiments examined how machining factors affected a redesigned single-point cutting tool. Texturing the tool’s rake surface without altering its physical qualities was achieved utilizing super-drilling and laser engraving technologies. The goal was to build a surface junction that would keep cutting fluid in contact with the tool longer, improving lubrication and cooling. Both standard and customized tools were used to compare cutting force, temperature, power usage, and surface polish. Magnified pictures from the scanning electron microscope were utilized to analyze tool wear in different places. The improved tool dramatically lowered mean cutting force, heat output, and power consumption in experiments. The textured tool produced continuous chips instead of discontinuous/burnt chips due to increased friction at the tool–chip interface. The updated tool improved lubrication and cooling with cutting fluid. Full article

Duplex stainless steels, well known for their excellent mechanical properties and high corrosion resistance, are used in high concentration chloride environments. However, the formation of intermetallic phases when they are exposed to high temperatures for extended periods limits their application in such scenarios. Hence, to determine their mechanical behavior, a study was conducted to determine the optimum parameters for obtaining good strength and hardness in duplex stainless steel. The Gleeble Physical testing system was used to test 2002 duplex stainless steel under hot compression while varying strain, strain rate, and temperature. Using an L9 orthogonal array, the optimal parameters for achieving high strength and hardness were arrived at using Taguchi techniques. It was identified that, at 1000 °C, a 10 s⁻¹ strain rate in samples strained to 60% provided the best results. Lastly, the microstructure was analyzed and correlated with the experimental results.

Brakes are essential parts of any system that involves motion. A few seconds are spent applying the brake, accumulating enough force to retard a system. In case of emergency stops, we need an efficient braking system that acts quickly and safely to avoid any mishaps. This work aims to develop a prototype of an instantaneous braking system, which can stop the motion of a rotating member. The operating principle of the device is the electromagnetic actuation of a solenoid. The actuation of a solenoid is simple and instantaneous. As a result, we could achieve immediate braking of a rotating member. Full article

Natural fiber composites are gaining popularity in manufacturing due to their cost-effectiveness, sustainability, reusability, and eco-friendly nature. Kenaf fiber is increasingly used as a reinforcing component in organic fiber-strengthened polymers for engineering purposes. Drilling is a crucial machining process used to create holes in composite constructions for the easier assembly of complex parts. Limited research has focused on drilling organic fiber-strengthened materials, as indicated by literature surveys. Consequently, this study investigates the drilling of weaved kenaf fiber-augmented polymeric composites. The study assesses the impact of drill bit varieties and cutting settings on delamination size and thrust force in poly (lactic acid) (PLA) composites supplemented with kenaf fibers. The investigation revealed that drill bit selection significantly influences surface finish and delamination index. Feed is the cutting variable that, when drilling kenaf fiber-reinforced materials, has the most impact on the thrust force for every drill bit. When using an HSS twisting drill with the Coro Drill-856 (CD-856), the thrust force produced is less than when using the Coro Drill (CD-854) design. Full article

This study focuses on metal inert gas welding for nickel alloy additive manufacturing using both cold metal transfer (CMT) and pulse multi control (PMT). For both single- and dual-bead deposition, the key parameters (current, travel speed, feed, weave, and height offset) were tuned. A hollow square component of 20 mm in height, 60 mm side length, and 16 mm width was created using these measurements. A macrostructural study demonstrated that flawless accuracy in geometry was attained by both PMT and CMT. In comparison to PMT, CMT specimens showed increased interlayer hardness but decreased hardness in the deposited layers. These changes were explained by modifications in eutectic phase size, distribution, and partial dissolution at the contact. For the wire arc additive manufacturing of nickel alloy components, pulse multi control is preferred over cold metal transfer. Full article

This study aims to explore the viability of adding a hybrid blend of eggshell and banana fibers treated with NaOH to improve the structural characteristics of epoxy composites. In order to determine their appropriateness for different applications, the study includes assessments of mechanical performance, water permeability, and heat transfer properties. Chicken eggshell was used to make calcined eggshell particulate (CEP), and bananas were used to obtain processed banana fibers (TBF). For the creation of bio-composites, NaOH-treated banana fiber (30 wt.%) was integrated into an epoxy matrix with different weight percentages of CEP (like 0, 4, 8, 12, 16, and 20 wt.%) through the hand layup with a vacuum backing technique. Examination of the data revealed that, in comparison to epoxy with no reinforcement, the addition of bio-fillers improved the thermal insulation (4 wt.% of CEP exhibits 0.052 W/mk), water absorption (4 wt.% of CEP produced 5.31%), flexural strength (20 wt.% of CEP exhibit 36.57 MPa), and modulus (12 wt.% of CEP exhibit 300.12 MPa) of the hybrids. This suggests that by lowering the conductivity of the bio-based composites, the inclusion of these bio-based reinforcements improved their thermal insulation ability. The resistance to temperature fluctuations is stronger when there is less thermal conductivity. Full article

This study used the salt spray test (SST) method to analyze the corrosion reaction of friction stir welded (FSW) alloys that are different from each other, including AA5052-H32 and AA6061-T6. To understand the overall and specific corrosion behaviour of the parent metals (PMs) and the FSW joints, the SST was carried out. The findings demonstrate that the microstructure of the various zones of the FSW joint varied noticeably, which in part influenced how each zone corroded in NaCl solution. The study determined the weight reduction and degradation rate of the stir zone relative to the PMs in the welded sample. Full article

Creating environmentally friendly and renewable resources for various industrial uses has attracted increasing attention over the past few years. The thermal and mechanical features of epoxy-based composites filled with coir powder, an organic and sustainable fiber made from coconut husks, are examined in this work. The current study focuses on the thermo-mechanical performance of epoxy matrix composites with coir filler in the micrometer range. Tension, flexural, and dynamic mechanical analysis were all carried out to characterize and forecast the thermal behavior of the micro-composites and pure polymers. According to the findings of this study, 8 and 6 wt.% of coir filler-based composites exhibit the highest tensile and flexural strengths of 41.36 MPa and 171.24 MPa, respectively. In the case of dynamic mechanical analysis, 8 wt.% filler had the highest storage modulus of 1214.98 MPa. The results demonstrate that the damping factor increases dramatically as the temperature rises and reaches its maximum value after the glass transition section. Additionally, including coir powder improves the composites’ thermal insulation capabilities, indicating their promise in demanding thermal resistance and insulation. Full article

The important properties of natural composites include but are not limited to their strength-to-weight ratio, durability and biodegradability. Natural composites are inhomogeneous by nature; drilling operations are difficult because the drill bit must alternately pierce through the layers of the matrix and fibers. This may cause delamination, fibers are pulled out and the matrix breaks, etc. In numerous types of research, it is seen that the spindle speed, drill diameter and drill geometry greatly influence the delamination factor and feed rate, affecting the surface roughness. In this review, the impact of the drilling and milling parameters on various natural-fiber-reinforced composites are taken into account and assessed. Full article

Recyclable yarn has become increasingly significant because of growing environmental consciousness and the necessity to acquire or enhance the qualities of woven materials in the years to come. A cotton yarn’s tensile strength, rip strength, and permeability to air were examined to obtain the intended outcomes. The experiment was carried out on specimens with almost identical structures, and the impact of the weaving and various weft materials was evaluated. This endeavor aims to find the right blend or blends of regenerated fibers to substitute 100% cotton garments. The mechanical strength and physiological characteristics of Tencel textiles mixed with other regenerate cellulose yarns were compared to those of 100% cotton to attain the same or possibly superior end qualities. Thus, cotton fibers, viscosity, Tencel, modal, and hemp were used. Standard thread counts of 20 tex were used to make mixed plain woven textiles made of 100% cotton and 50:50 mixes of Tencel with other regenerating materials. The ergonomic qualities, such as air permeability, and mechanical characteristics (tension and tearing assets, pilling, abrasion resistance, and warp- and weft-wise) were assessed. It has been discovered that textiles combined with Tencel perform better than cotton ones. Consequently, it may be said that 100% cotton textiles can be replaced with a Tencel combination, using these regenerating fibers. Full article

Natural fibre–polymer composites are widely used because they are economical and ecologically beneficial in a variety of applications. In order to improve its performance, this study focuses on examining the mechanical characteristics of an epoxy composite material that has been reinforced with banana fibre mats that have undergone NaOH treatment. Additionally, using various configurations both with and without eggshell powder (ESP), the compression moulding method was used to fabricate and investigate the impact of ESP on these mechanical qualities. The results showed that the composite with 25 weight percent banana fibre and 2.5 weight percent ESP had the maximum tensile strength (31.21 MPa), bending strength (33.69 MPa), and impact strength (2.84 kJ/m²). Strong interfacial adhesion between the banana and eggshell components was discovered via the microscopic examination of shattered surfaces. Notably, compared to untreated banana composites, the alkaline-treated banana materials showed fewer occurrences of pull-outs and fractures, leading to noticeably better mechanical performance.

Partial vaned diffusers (PVDs) play a pivotal role in optimizing the performance of turbomachinery systems by efficiently managing fluid flow and pressure differentials. This study delves into the geometric configurations of partial vaned diffusers, examining how variations in vane positioning impact performance. In this study, a PVD is attached either along the hub side (PHVD) or shroud side (PSVD), and a comparison is made between these configurations. Computational fluid dynamics simulations are carried out using ANSYS CFX to elucidate the complex flow patterns within these diffusers for two different mass flow rates, namely 0.30 kg/s and 0.90 kg/s. Flow parameters like pressure, total pressure in the stationary frame, meridional velocity, and velocity are measured. The flow in PSVD is observed to be uniform and the rise in pressure in PSVD is observed to improve by around 4.5% with respect to PHVD. Other flow parameters such as meridional velocity and total pressure are in favor of PSVD. Full article

The goal of this research is to analyze the effects of a partial thermal barrier coating on piston temperature distribution in homogeneous charge compression ignition (HCCI) engines, which are investigated using La₂Zr₂O₇ nanocoating with 1 mm thickness for numerical analysis. The thermal assessments of both conventional and coated pistons were performed using ANSYS V16. Engine testing was conducted on a single-cylinder, water-cooled CI engine for both the coated and conventional casings. According to the analytical results, the coated piston component’s surface temperature increased to 53 °C, which increased the temperature of the air–fuel mixture in the crevice and wall quenching zones. As a result, cold start HC emissions dramatically drop without impacting engine performance compared to normal engines. The maximum HC emission reduction over the standard engine was 43.2%.

The rapid growth of urban cities and industries has resulted in huge amounts of potentially harmful waste being released into the atmosphere. One form of hazard is noise/sound. Noise cannot be controlled in automobile industries and urban areas, which include traffic, railway stations, and markets. But it can be converted into a useful form through advanced material usage. One of the materials is piezoelectric material. Strain can be produced through vibration caused by sound, which, in turn, produces electrical energy. Hence, the objective of this research was to harvest electrical energy from hazardous sounds released from industries. Electrical energy was generated through systematic experiments using piezoelectric sensors. The experimental results revealed that the magnitude of 90 dB sound produced up to 2 volts through a single piezoelectric sensor. We can generate more energy by increasing the number of sensors as this material is cost effective. The numerical model was also effectively replicated and good agreement was obtained between the experimental and numerical frequency sound curves. Full article

This study explores the impact of silica nanoparticles on jute fiber-reinforced composites with epoxy resin matrices. Silica nanoparticles were synthesized at three concentrations (3%, 6%, and 9%) and incorporated into composites at varying fiber–resin weight ratios. The composites were subjected to tests for tensile strength, flexural strength, impact strength, and hardness. The Taguchi signal-to-noise ratio method was employed for optimization. Results indicate that a 9% addition of silica nanoparticles significantly enhances the mechanical properties of jute fiber-reinforced composites. Tensile and flexural strength increased with higher silica nanoparticle content, while impact strength and hardness also improved. Notably, a 9% silica addition achieved a maximum tensile strength of 72 MPa, resulting in a 10% increase over that yielded by the 3% addition. Flexural and impact strengths improved by 23% and 20%, respectively, when compared to the 3% silica addition. Furthermore, a neural network model accurately predicted the composite’s mechanical characteristics with 100% accuracy. These findings hold promise for the automobile and aircraft industries, as they require high-performance materials. The integration of jute fibers and silica nanoparticles into composites offers a sustainable and eco-friendly alternative to conventional materials. The enhancement strategy employed in this analysis can be applied to enhance the mechanical properties of other composite materials. Full article

Recently, the utilization and research of biodiesel has become increasingly popular due to its reduced emissions, lower cost, and potential for achieving energy independence. A promising application of biodiesel is in diesel engines, where it can be used as a substitute for traditional petroleum-based diesel fuel. Camelina sativa is an oil seed crop with prospective uses in biodiesel extraction due to its high crop harvest in a year, good net energy ratio, the considerable oil content in its seed, and lower oil extraction expenses. Biodiesel derived from camelina sativa L. is prepared via transesterification. In this study, the prepared biodiesel is blended with diesel at various proportions and is used in an engine to investigate its combustion performance and emission characteristics. From the results, it is evident that the CMB 20 blend (20% of camelina biodiesel and 80% of diesel) shows the better performance among all of the blends used. The brake thermal efficiency of CMB 20 is 23.45%, its specific fuel consumption is 0.355 kW/kg hr, and it also produced less emissions when compared to other blends. Full article

This work explored the possibility of producing a compositional functionally graded material (FGM) between mild steel and Inconel 625. An in-house fabricated, dual filler wire tungsten inert gas welding set up was used to deposit weld beads on a mild steel substrate. Filler wire feed rates were controlled independently and the combinations of filler material volumes, i.e., mild steel–Inconel 625 of (100:0), (75:25), (50:50), (25:75), and (0:100) were fed into the arc simultaneously and individual weld beads deposited. Preliminary studies revealed that defect free completely fused new alloys were formed and intermetallic phases rich in Nb observed. Compositional analysis showed that the content of each element changed from one alloy to the other gradually, smoothly indicating the feasibility of a mild steel–Inconel 625 functionally graded material.

The monitoring of machining has been the focus of widespread research in recent years because of its substantial contribution to manufacturing process automation. To maximise productivity, the spindle speed and feed have been increased, which has increased noise and temperature generation in the workpiece and tool. Such loud noise levels are uncomfortable for the operators, create stress, and have negative health effects, which reduces productivity. Controlling the temperature and noise produced during milling is crucial. Among its several series, the aluminium alloy 7075 (AA7075) is one of the strong alloys utilised in aircraft structural components. Hence, the present work examines the effect of spindle speed, feed, and depth of cut on noise and temperature generation during the end-milling of an AA7075 plate with 0.25-inch thickness. The sound and temperature were measured for both up- and down-milling processes and compared. In up-milling, the temperature and noise varied from 32.9 to 50.6 °C and 87.5 to 95 dB and the same were varied from 30.6 to 36.2 °C and 89.6 to 93.9 dB for down-milling. Finally, it was recommended that down-milling is the best process with low noise and temperature generation. Full article

With over 9 million additional tons of plastic waste entering the oceans each year, 165 million tons of plastic waste have already defiled our oceans. Considering that just 9% of plastic is recycled, the rest of the waste contaminates the environment or is dumped in landfills, where it can take up to 500 years to degrade while releasing hazardous chemicals into the soil. The bioplastics prepared in this study were obtained from tapioca and sweet potato using plasticizers like glycerol in various combinations. The biodegradability and mechanical and physical properties were analyzed. The tensile strengths of the prepared bioplastic films were 4.25 and 2.35 MPa with elongation at break (EAB) of 39.5% and 25.4% for tapioca and sweet potato bioplastics, respectively. The biodegradability of the films was examined, and thus, the obtained bioplastics in the study are shown to be a good alternative to the existing plastics. Full article

Shape Memory Alloys (SMAs) are a class of metallic alloys that have the ability to return to their original shape after being deformed. NiTi (nickel–titanium) alloy a type of shape memory alloy that possesses unique properties such as remembering its shape, biocompatibility, and super-elasticity. These SMAs have the ability to deform when heated and regain their original shape when allowed to cool. The disadvantage of a fuse is that it can only be used once. By replacing a wire that melts with a NiTi shape memory alloy, we can turn it into a switch that opens when an excessive current (which leads to an increase in temperature of the wire) is applied. Magnets keep the circuit closed. When the wire heats up, the spring-shaped coil shrinks, which opens the circuit. The circuit can then be closed manually once the problems are rectified.

Natural fiber-based polymer composite has great potential and is in high demand due to its high specific strength, low carcinogenic nature and economic market value. Tamarindus Fruit Fiber (TFF) has low density, high tensile strength and is easily available. It is one of the industrial waste materials. Polylactic acid (PLA) possesses an entangled coherence with fiber, since it is more compatible. A sample was prepared by integrating TFF as fiber and PLA as the binding agent. The fiber variations in all samples were 10 to 50 wt.% step by 10 wt.%. A pure PLA sample was also fabricated for the purpose of comparison. Mechanical properties such as tensile strength, flexural strength, impact and hardness have been evaluated. It was revealed that TFF reinforcement increased the mechanical properties of the samples. The highest mechanical properties were observed in Sample S5, which had 40 wt.% TFF and 60 wt.% PLA. Fracture failure was found using fractographic analysis. In conclusion, this study demonstrates the potential of utilizing TFF as an agricultural waste product for enhancing the mechanical properties of biodegradable polymer composites. These sustainable compositions of materials have been used for many applications in various industries, including packaging, automotive, and construction, while also providing an environmentally friendly solution for agricultural waste products.

When it comes to precision and functional requirements, such materials need to be machined. The aim of this study was to investigate the machinability behavior of Mg/B₄C metal matrix composite (MMC) through end-milling experiments. Different deformation behaviors of the composite were studied by varying the volume percentage of B₄C reinforcement between 5% and 10%. Using a milling tool dynamometer, the cutting forces on the tool were examined for various milling parameters. Moreover, Talysurf roughness was used to analyze the machined surface under each cutting parameter, and scanning electron microscopy was used to study the chips produced under different cutting conditions.

This study’s objective is to turn AISI 304 stainless steel (304 SS) utilizing the Minimum Quantity Lubrication (MQL) technique while comparing the outcomes to dry turning. Based on the responses, cutting force, surface roughness, and temperature, three process parameters, speed, feed, and depth of cut (doc), were optimized and regressed for both dry and wet conditions. Dry turning and wet turning are carried out, and the responses are noted. Later, the surface roughness (R_a) of the machined component under both conditions is tested with the help of a surface roughness measuring instrument. The surface roughness of the component under wet turning is reduced to 0.5958 μm from 0.7425 μm with dry turning. The cutting temperature was controlled very well in wet turning with a value of 61.21 °C than with a value of 84.16 °C in the case of dry turning. The cutting force developed during dry turning is reduced by applying a mist of oil, which lubricates the surface, thereby reducing the cutting force to a value of 4.987 Kgf from 5.254 kgf. Corn oil produces better results and can be used as an alternate cutting fluid. Full article

Optimization approaches provide a strong foundation for analyzing and forecasting actions within a selected domain. This approach may be used to assess the extent of the effect of input variables on responses. There are several optimization tools and methodologies available, but each has its numerical approach and degree of accuracy with experimental data. As a result, several optimization methods are constantly evolving, and many new studies have focused on them. This study analyzes new optimization approaches employed to handle the issue of the location and size of distributed generating units for diverse applications, particularly focusing on tribological aspects. In addition, this work examines the modern technological, technical, economic, and regulatory factors that have created interest in distributed generation integration, as well as an overview of the challenges that must be overcome. Finally, it evaluates all relevant strategies for integrating dispersed generation from renewable energy sources using optimization techniques. The main methods of Response Surface Methodology (RSM) and the Taguchi optimization technique were chosen because they have been used in many technical investigations and provide more significant predictions.

This work explores the fiber laser cutting of AISI 431 martensitic steel using an optimized technique of RSM-BBD. A significant increase in gas pressure, power, and cutting speed improved material removal by 62.4%. Surface roughness was reduced by 56.7 percent with decreasing cutting speed, gas pressure, and laser power. The microhardness of the ablated surface was increased due to the resolidification of the molten layer. Surface topography analysis confirmed the machined samples’ surface roughness and quality. The research aims to understand AISI 431’s machinability and contribute to the improvement of component quality, especially in orthopedic implants and automotive component applications. Full article

Jute fiber, a sustainable and abundant material, has garnered attention as a potential reinforcement in composites. This study focuses on enhancing the jute fiber composite strength through the inclusion of Al₂O₃ nanoparticles at varying levels. Mechanical properties were rigorously examined to evaluate their suitability for high-stress applications. This research encompassed assessments of hardness, flexural strength, tensile strength, and impact resistance. The results indicate that the incorporation of Al₂O₃ nanoparticles significantly improves the composite mechanical properties. Increasing the Al₂O₃ content elevates hardness, enhancing resistance to indentation. Flexural strength tests highlight the increased stiffness and deformation resistance, rendering the composites suitable for structural use. Additionally, tensile tests reveal an enhanced load-bearing capacity under tension with higher Al₂O₃ percentages. An improved impact resistance confirms the durability and the ability to withstand sudden shocks. These findings present promising opportunities for utilizing Al₂O₃-reinforced jute fiber composites in industries requiring high-strength materials, such as the automotive, aerospace, construction, and sports equipment manufacturing industries, combining sustainability with enhanced mechanical properties.

Sisal-fiber-reinforced composites have garnered significant attention across various industries owing to their favorable attributes, including cost-effectiveness, biodegradability, and lightweight characteristics. Nevertheless, the need to enhance their mechanical and tribological properties has become imperative to meet the growing demand for high-performance materials. This study explores the impact of tungsten carbide (WC) particle reinforcement on the mechanical and tribological properties of sisal fiber composites. Composites were prepared by incorporating varying WC percentages (3%, 6%, and 9%) into the sisal-fiber–epoxy matrix. Flexural tests revealed a notable increase in flexural strength as WC content increased. Izod impact tests demonstrated superior impact resistance with higher WC content. Furthermore, pin-on-disc wear testing identified enhanced wear resistance in composites containing 9% WC reinforcement. These findings illustrate the potential of WC-reinforced composites for applications necessitating improved strength, impact resistance, and wear resistance, positioning them as promising materials for diverse industries.

Wire electric discharge machine (WEDM) is a process used popularly in microsystems, tool and die industries, medicine, transportation, and spacecrafts to create intricate portions with high dimensional accuracy and surface finish. It is employed to process superalloys and materials made of composites which are conductive and strong materials. From the literature, an analysis of the WEDM process on different materials revealed that there were many variables involved and that each process parameter influences the different response variables. The removal process of a spark discharge for an inclined angle during the cutting of 3D profiles has different applications. Also, types of dielectric fluid, and the influence of wire material, diameter and pressure, wire tension, feed, Ton, Toff, current, and voltage on machining characteristics—like kerf, MRR, wire wear, surface finish and its characteristics, dimensional deviations, and corner errors—and on a variety of materials like Inconel, nickel, titanium, WC, steels, and other superalloys and composites (MMCs and CMCs) during taper WEDM were reviewed.

The utilization of conventional fossil fuel-based energy for power generation is associated with various issues, such as greenhouse gas emissions, rising costs, and scarcity of resources. Renewable energy sources offer a solution to these problems. Although solar photovoltaic technologies have been leading the way in this area, the output of solar cells is constrained by optical losses. Surface texturing reduces reflectance, increasing the absorbance of solar cells. Therefore, it is necessary to obtain proper values of texturing parameters before fabricating the solar cell. Software simulation tools can help to do this. In the present work, the PC1D 5.0 tool is used to obtain an optimum texture thickness and angle for a solar cell of a 100 cm² cross-sectional area. For the texture angle of 65°, the optimum texture was found to be 4 µm. Full article

Friction stir processing (FSP) is a solid-state processing technique used to refine the microstructures of metallic alloys. It involves inserting a rotating tool into the material, which generates heat and plastic deformation, leading to the recrystallization and refinement of the microstructure. The aluminium alloy 7050 is a high-strength alloy possessing good corrosion resistance, and is commonly used in aerospace applications. By incorporating SiC particles into the alloy with different percentiles of 0 to 1%, the resulting composite can have improved mechanical properties, such as higher strength and stiffness, as well as increased wear resistance. Mechanical testing and optical metallographic characterization were conducted. The test results showed that weldments have improved mechanical properties compared to the base material, making them suitable for high-strength and low-weight applications. Full article

This study aims to enhance the mechanical and wear properties of hybrid nanocomposites by incorporating SiC nanoparticles and glass fibers into an epoxy resin matrix, utilizing a neural network for optimization. The mechanical properties were evaluated via flexural, impact, and wear tests. SiC nanoparticle concentrations were varied at three levels using the Taguchi technique. The results were optimized with the Taguchi signal-to-noise ratio approach. Regression analysis was used to determine the wear rate, flexural strength, and impact properties of the composites. SiC reinforcement significantly influenced the flexural and impact strength, along with wear resistance. The composition with 2% SiC showed a flexural strength of 95 MPa, while 4% and 6% SiC compositions exhibited strengths of 110.5 MPa and 125 MPa, respectively. The impact strength followed a similar trend. The wear test results demonstrated a decrease in the specific wear rate (Swr) and coefficient of friction (CoF) with an increasing SiC nanoparticle percentage. The optimal parameters were identified as 6% SiC nanoparticle loading, 15 N load, 160 RPM rotation speed, and a 40.2 mm sliding distance. The enhancement in impact strength is attributed to SiC nanoparticle reinforcement. The results were further refined using an artificial neural network for improved predictability. This research underscores the effectiveness of hybrid nanocomposites with SiC nanoparticles and glass fibers, as well as the potential of neural networks for process optimization, benefiting industries requiring high-performance materials.

Hand-arm vibration is a significant occupational hazard commonly faced by industrial workers, particularly those in foundries engaged in fettling activities. The vibration exposure can result in various health problems, such as hand-arm vibration syndrome (HAVS), carpal tunnel syndrome, and other musculoskeletal disorders. Therefore, it is essential to evaluate workers’ vibration environment and exposure levels to prevent such health issues. At first, the present study explored a different type of vibration exposure followed by vibration syndrome and vibration measurement methods. A case study was considered wherein the comparative analysis between pneumatic and swing grinders was performed between vibration magnitude, particularly in the fettling shop. The results revealed that the pneumatic hand grinder worker experienced a vibration magnitude of 3.6 m/s² at 208 exposure points. In comparison, the swing grinder had a magnitude of 6.5 m/s² at 668 exposure points for an 8 h workday. It can be noted that regulatory bodies such as ISO 5349 recommend an exposure vibration magnitude of 5 m/s² for an 8 h workday and in the present context, these exposure levels were found to be higher than the standard limits. Accordingly, proper recommendations to sustain these levels within the limits are suggested. Such recommendations will protect workers from health hazards and help employers avoid costly compensation claims and legal liabilities. This study emphasizes the importance of addressing hand-arm vibration in the workplace for a safe working environment. Full article

Machining is a critical aspect of metalworking since it is used to cut metal. Machine tools, particularly cutting tools, are critical in metalworking for successful metal cutting. They have a significant role in developing distinct shapes and forms. Machining has become more crucial in modern automated manufacturing systems because of the massive upsurge in production time and the necessity to offset the high capital cost. Specifically, the Taguchi approach is used in this experiment because it uses an orthogonal array to investigate the parameters through a fixed number of experiments. In this case, three parameters (speed, depth of cut, and feed) were combined to produce nine possible result combinations. Stainless steel and mild steel are machined with the help of a ceramic tool insert with certain combinations. This is performed to estimate tool wear and surface roughness. The comparative study was conducted for two different materials: stainless steel (SS) and mild steel (MS). Full article
