Cutting fluids should be chosen by acidic nature test and viscosity test. It should have proper lubricity and act as a coolant. Vegetable oils like groundnut, coconut, and sunflower are considered to check their properties. Among these oils, groundnut and coconut oils were selected based on their properties. Experimental studies on the performances of both newly developed environmentally friendly vegetable-based cutting fluids (coconut oil and ground nut oil) and commercial cutting fluids in turning processes were reported. Performances of cutting fluids were compared with respect to surface roughness, cutting and feed forces and tool wear during longitudinal turning ofEN8 SAE/AISI 1040 steel. Experimental results were also compared with dry cutting conditions. Based on the results, the best-cutting fluid was selected.</p> Sakthi Vadivel K, Sivaraj C, Vigneshwaran K Copyright (c) 2022 Journal of Manufacturing Engineering Tue, 01 Mar 2022 00:00:00 +0000 ENGINEERING APPLICATIONS OF CHEMICALLY ACTIVATED CARBON COMPOSITES FROM AGROWASTES OF PALM KERNEL AND COCONUT SHELLS <p>Epoxy/activated carbon composites of particle sizes (60, 105, 150μm) and reinforcement weight percentages of (2, 4, 6 and 8) have been developed and evaluated for engineering applications. The physicomechanical properties were determined according to ASTM standard methods. Density decreased with an increase in reinforcement weight percentage. 2% weight increment of the particle sizes of the chemically activated carbon fillers yielded tensile and flexural strengths higher than that of the selected commercial brake pads (CB1) and (CB2), with the tensile strength of 4.84 and 6.58MPa, the flexural strength of 12.84 and 21.61MPa respectively while the hardness results compared well with the commercial brake pads samples. In general, from the standpoint of its tensile strength, %elongation at break, flexural strength, and hardness properties, these new formulations can find applications in aerospace and automobile industries where lightweight, high strength materials are sought after, hence a potential organic friction lining precursor for brake pad manufacture.</p> Leonard Maduabuchi Akuwueke, Ossia Chinwuba Victor, Nwosu Ugochukwu Harold Copyright (c) 2022 Journal of Manufacturing Engineering Tue, 01 Mar 2022 00:00:00 +0000 OPTIMIZATION OF PROCESS PARAMETERS IN ROLLING OPERATION FOR MANUFACTURING OF THERMOMECHANICALLY TREATED BAR USING MINITAB AND MATLAB SOFTWARE <p>At low cost, designing high-quality products and process is a challenge to the engineers. For the manufacturing of TMT bars, the critical quality parameter is yield strength. This study aims to choose the optimal variables that will achieve the needed yield strength. In this research work, the use of the Taguchi Method and the concept of DOE (Design of experiment) for optimization of Thermo Mechanical Treatment Process parameter. In the plant, readings have been taken by Taguchi Method and by using MINITAB and MATLAB Software to find optimal combination factors. For optimizing the process parameters ANOVA, S/N ratio (Signal to noise ratio), and orthogonal array have been utilized. Optimum values have been obtained with the help of graphs as well as a confirmation experiment.</p> Satish kumar sao sao Copyright (c) 2022 Journal of Manufacturing Engineering Tue, 01 Mar 2022 00:00:00 +0000 PERFORMANCE EVALUATION OF SOLAR AIR HEATER USING INCLINE BAFFLES <p>To investigate the solar air heater’s (SAH) effectiveness, experiments are conducted using flat plates and artificially roughened plate in terms of Inclined and Winglet baffles over the collector surface. This proposed system collector plate comprises Inclined and Winglet ribs and serves as an artificial roughness generator. Airflow rates of 0.01, 0.02, &amp; 0.03kg/s are used in the experiment. To determine the improvement in the proposed work, the experimental results are compared with flat plate SAH. This proposed work offers greater efficiency, useful energy gain, and lower top heat loss than a conventional SAH. The airflow rate of 0.03kg/s gives the topmost efficiency and useful energy gain. The experimental day’s average efficiency of a SAH with Incline baffles is 32.6 %, 53.6 %, and 61.9 %, respectively, for the flow rates examined. For the same flow rates, it is 37.4 %, 29.6 %, and 24.39 % more effective than a flat surface SAH. For the same investigated air flow rates, the proposed system gains 37.7 %, 27.63 %, and 23.63 % more energy than flat plate SAH. Substantial reductions in Top losses of up to 8.20 %, 6.55 %, &amp; 7.65 % have been reported at the specified flow rates. Energy metrics and economic study performed shows the payback time, Production factor, Life cycle conversion efficiency and economic values of the proposed SAH is optimum.</p> Karthik S, Gokul S Copyright (c) 2022 Journal of Manufacturing Engineering Tue, 01 Mar 2022 00:00:00 +0000 EXPERIMENTAL INVESTIGATION AND ANALYSIS OF SURFACE ROUGHNESS PARAMETERS IN HARD TURNING OF AISI D2 STEEL USING COATED CARBIDE TOOLS <p>In the present work, hard turning of AISID2 Steel were carried out on CNC turning centre using TiCN coated carbide tools to investigate the effect of cutting parameters on surface roughness parameters (Ra, Rq, Rz) The statistical models were developed using the Taguchi method to find the effect of cutting parameters (speed, feed, and depth of cut) on surface roughness parameters. L9 orthogonal array is designed for the experiments and experiments were carried out for one, two and three passes to evaluate the optimum roughness value of the surface roughness parameters. It was observed from the results that the feed rate played an important role with surface parameters.</p> Vatsal Maisuriya K, Ruchit Kantharia, Rathod K B Copyright (c) 2022 Journal of Manufacturing Engineering Tue, 01 Mar 2022 00:00:00 +0000
