The data generated are useful for operators in the machining process in the manufacturing industry. Simulations and experimental methods are used, and data generated from cutting force sensors are validated using mathematical models commonly used for cutting force calculations. From the obtained data, the characteristics of the cutting force influenced by the cutting speed of the machining process are further analysed. The material is a PEEK composite used by the manufacturing industry. The tool used is a material-type high-speed tool steel end mill. By using a machine-type table tilting 5-axis mill for the rough machining process, the variation in cutting speed affects the tool cutting force at each shear angle. The data showed that the lowest cutting speed produces a high cutting force on the x-axis component. In this component, the largest value is 39.73 N at a cutting speed of 18.84 m/min; at the y-axis at the same cutting speed, the largest cutting force value is 79.20 N. The z-axis component value is 16,405 N, which exhibits the lowest cut force value compared to the increase in the speed of the other cuts used in the study. The increase in tool cutting speed does not always increase the cutting force of each machining axis.","PeriodicalId":37784,"journal":{"name":"International Journal of Mechanical Engineering and Robotics Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67497649","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}

However, they still use the principles of traditional vehicles in terms of design and operation. This work proposes an adaptive transportation system based on autonomous POD vehicles, and investigates a major aspect of its operation. The PODs used in the proposed system can be considered a variant version of existing autonomous PODs. However, their unique design and concept of operation enable them to operate more efficiently than existing PODs. The proposed system involves docking and undocking of these PODs based on passengers’ demands. However, during the merging process, undesired collisions could happen due to unforeseen conditions. If the approach speed is high enough, it could induce damage to the vehicles. This work investigates some possible scenarios of the potential collisions that could happen between these PODs during the merging process. Based on these scenarios, the allowed safe approach speeds are determined. These speeds can help in designing the operation of the proposed transportation system. Some of the variables considered in this work include; type of body material, shell thickness, impact speed, stress, deformation, and absorbed energy. The safe design merging speeds have been determined under different conditions.","PeriodicalId":37784,"journal":{"name":"International Journal of Mechanical Engineering and Robotics Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67496352","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}

Today, implementation of environmental protection policies by the governments has set new directions for engine development. The fuel efficiency of the CI engine is improved to minimize exhaust gas, and post-processing in exhaust gas systems performance enhanced to reduce the emission of toxic contaminants. A common rail direct injection (CRDI) diesel system injects high-pressure fuel directly into the combustion chamber via Common-rail injector. Through this process, complete combustion is achieved in the combustion chamber. The common-rail injector is a critical in terms of combustion emission. This study examined the characteristics of CRDI injector parts and carried out comparative tests on injectors under normal and abnormal conditions. The tests include a compressive pressure test, idle speed comparison test, and injector correction test. Uniform output between cylinders was observed for the normal injector, whereas cylinders with defective injectors showed (-) non-uniformity. Injector correction involved increasing the amount of injected fuel to compensate for the insufficient force between cylinders. Based on the injector current wave, this method of injector correction was found to increase the energizing time by about 0.2 ms in the idle section. The injector fuel return flow test demonstrated an increase in return flow from defective injectors, which can be traced to internal oil fuel leaks or the higher amount of injected fuel.","PeriodicalId":37784,"journal":{"name":"International Journal of Mechanical Engineering and Robotics Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67496377","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}

The current study investigates the effect of changing bend angle on the evaporative cooling of an airstream via spray of water in fogging mode. The experimental Particle image velocimetry (PIV) technique has been implemented for visualizing the secondary flow layout when an air-water mixture travels through the bend duct. The bend angles considered are (45 o , 90 o and 135 o ) at velocities of (5, 3.75 and 2.5 m/s) for air flow through 50 cm square duct. PIV results manifested that a single pair of counter rotating vortices appears at 45 o bend angle, while the other two bend angles evinced two pairs of vortices (four-cell pattern) across the duct cross-section. The water spray was set to tilt at three orientations, namely (45 o , 0 o and – 45 o ) to the axial flow direction to suit the change in bend angle. ANSYS FLUENT 19.R1is used in numerical simulation with RNG-k-ε turbulent model to study the spray characteristics which impacts the cooling process. The best cooling of the airstream is obtained when the water is sprayed axially, i.e. at 0 o , prior to the 135 o bent duct ranking 30% reduction in temperature corresponding to 6.5% improvement in heat transfer between the two phases.","PeriodicalId":37784,"journal":{"name":"International Journal of Mechanical Engineering and Robotics Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67496525","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}
