For the modelling and study of the versatile composite manipulators, a three-noded beam feature is used. The effects of the taper angles of tapered flexible composite manipulators on the final product effector movement and vibration has been considered. In present work CATIA V5 is used to model the flexible single link robotic arm and static structural analysis to find stress and total deformation, dynamic analysis is carried out to find different modes, corresponding frequency, and life estimation of flexible single and double link robotic arm and also material optimization is done using different material composition for structural steel, aluminium and CFRP composite material using ANSYS WORKBENCH 18.2 (Finite Element Approach) for life estimation and evaluation using analytical approach.","PeriodicalId":39575,"journal":{"name":"Journal of Mines, Metals and Fuels","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47915566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kenaf, jute, Kemp, and other types of reinforcing fibres are frequently utilized and come in strips. The design and analysis of the mechanical characteristics of the Kenaf fibre reinforced composite is the primary goal of this project. Different combinations of fibre and resin are examined for their various mechanical qualities, such as impact resistance, flexural strength, and tensile strength. By altering the fibre orientation and boosting impact strength, the composite is created. By altering the fibre orientation and boosting impact strength, the composite is created. The composite is personally examined using a variety of testing tools, and it is also examined using design software like Ansys. This research aims to increase the composite’s impact strength by adjusting the fibre length. The hydrogen peroxide solution is also coated on the composite before the tests are run. Comparisons are made between the experimental findings for coated and uncoated composites.","PeriodicalId":39575,"journal":{"name":"Journal of Mines, Metals and Fuels","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46047945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent decades, there has been a surge in interest in studying various elements of the porous media. This enormous level of attention has resulted in a slew of research publications addressing a wide variety of issues affecting porous materials, including understanding their structure, deformation, and natural convective heat transport, to name a few. The investigate of the porous material is one of the classical topics in field of science. In this paper, we investigate the free convection in a trapezoidal porous enclosure with different Rayleigh numbers (10 1 ≤ Ra ≤ 103) and aspect ratios (0.25 ≤ H/L ≤ 1). The effect of Ra and AR on temperature contours, local and mean Nusselt numbers has been analyzed and presented. This provided a result in which the mean Nu increased by increasing the H/L ratio and Modified Ra. In addition, convection mode is dominant when Rayleigh number is high. The outcome results are differentiated with those found in the literature and were found to be in good accordance.\u0000 ","PeriodicalId":39575,"journal":{"name":"Journal of Mines, Metals and Fuels","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43828065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because honing is an abrasive operation, predicting the process outcome analytically is challenging. The steep peaks of a surface are eliminated during the plateau honing process, producing a reasonably plateau finish along with cross hatch pattern for retaining oil and increased bearing area. A cylinder liner is installed in an engine block to provide a cylindrical chamber where the piston may move extremely smooth. To obtain a honing pattern and good surface roughness, the machine setting plays an important role which includes many machine parameters like honing force, number of stokes, feed rate, processing time etc. So, in order to obtain an optimal machine set up, multiple trails on cylinder liners are done, which takes more time, and for each trail, one cylinder liner specimen is utilised, which results in the consumption of more cylinder liner solely for trail purposes. In this work, the key parameters effecting the surface roughness of cylinder liner are identified and optimal honing parameters (machine setup) are selected. FEA analysis is carried out to find the effect of pressure on the walls of cylinder liners. Based on the results of experiment, the optimal setting for honing machine is obtained for the selected surface roughness with less ovality and taper and also has less effect on cylinder liners.","PeriodicalId":39575,"journal":{"name":"Journal of Mines, Metals and Fuels","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44166704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are a lot of scopes to improve the properties of cutting tool materials to enhance their ability to machine challenging materials like heat resistant super alloys (HRSA). Reducing the grain size of cutting tool material powder to nano level may help to increase the strength, substrate hardness, Fracture toughness, and thermal conductivity of the cutting insert. This review studies different strategies used to develop nano powders for the cutting tool application. We observed that most of the studies focused on the latest powders used in cutting tool industries like tungsten carbide, boron carbide powders which are reduced as nano powders, pressed, and sintered with different techniques like hot isostatic pressing (HIP), Spark plasma sintering. Finally, the current research gaps and the future challenges in understanding the development of nano powders for cutting tool applications are critically discussed, providing an interpretation of the possible directions for scientific development in this field.","PeriodicalId":39575,"journal":{"name":"Journal of Mines, Metals and Fuels","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45620255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
