The advances in the field of Materials science and Technology have led to development of new materials with improved engineering properties even for commonly used materials. Even the strength and hardness of a variety of conventional engineering materials has increased many fold to keep pace with development of new materials. Sintered carbides are extensively used as cutting tool material, a material in machining a wide variety of work materials in present day machining industry with proven machining abilities compared to HSS tool and Cast alloy. But in machining of high strength temperature resistance alloys used in aerospace, marine and nuclear applications, they have failed miserably due to rapid wear. This has forced the machining Industry to bring in innovative changes in process design and application in terms of rigid machine tool and new cooling strategies. However, machining of these new classes of materials is still plagued by low productivity due to rapid wear. In the present work, uncoated Tungsten Carbide cutting tool inserts of geometry SNMG 120408-MR4 have been used. The inserts were cryogenically treated and were subjected to annealing in electric muffle furnace by pacing on refractory brick at temperatures 400oC, 600oC, 800oC. The samples showed appreciable improvement in hardness and microstructure study revealed that carbide phase distribution was fairly uniform with binder phase segregating slightly in few cases. Under all cutting velocities, Cryotreated and annealed inserts showed the highest tool life and wear resistance. Annealing has significant influence on the phases present in WC+Co inserts and subsequently influences their machining performance.","PeriodicalId":207087,"journal":{"name":"International Journal of Advanced Materials Manufacturing and Characterization","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130411759","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 loose vehicle transmission casing produces heavy vibration and noise. Noise and vibrations are the two technical indexes for the transmission failure. Truck transmission gearbox assembly is subjected to harmonic and meshing excitation. These excitation forces are the main reason of noise and vibration. The vehicle gearbox casing is mounted on chassis frame using connecting bolts fixture. 37 positional connecting bolts fixture were used to constraint the casing on chassis frame. This study is carried out in three stages. In first stage zero displacement constraint based boundary condition were used to evaluate the exact natural frequency and mode shapes. In second stage 4 fixture bolts were loosened, natural frequency and mode shapes were evaluated. In third stage all bolts of left positional view is unconstrained, natural frequency and mode shapes were evaluated. Reciprocity Principle was used to apply the loads on casing. The first 10 vibration mode shapes and natural frequencies were calculated using ANSYS 14.5. The study has practical importance for the structure optimization of gearbox casing. ANSYS 14.5 is used as FEA based analysis tool. The natural frequency for zero displacement condition varies from 1669 Hz to 2865 Hz. The simulation results were verified with experimental result available in literature.","PeriodicalId":207087,"journal":{"name":"International Journal of Advanced Materials Manufacturing and Characterization","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126327977","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 mechanical properties viz. tensile modulus, tensile strength, flexural modulus, flexural strength and micro-hardness are studied. For mechanical tests, ABS/ZnO composite materials are developed with 0, 5, 10, 15 and 20 wt% of filler. It is seen from the results that the tensile and flexural moduli increase with increase up to considered filler content, but the tensile strength and flexural strength increase up to 15 wt% and then start decreasing. The tribological behavior (friction coefficient and specific wear rate) of ABS composites filled with ZnO filler sliding against the steel counter face are investigated varying filler content (A), normal load (B) and sliding speed (C) with three levels of each parameter. The experiments are conducted on a multitribotester (block-on-roller configuration) using L27 orthogonal array (OA) of Taguchi analysis. To optimize the multiple responses (friction coefficient and specific wear rate), grey relational analysis is performed for the experimental results. It is seen from the analysis that the highest level of design parameters (A3B3C3) provides minimum friction coefficient and specific wear rate. The most influential factor which affects the tribological properties is normal load (B) followed by sliding speed (C) and filler content (A). Finally, a confirmation test is also carried out to validate the optimized results and it is seen that the grey relational grade is increased about 22% from initial to optimum conditions. The worn surfaces of ABS filled with micron-sized ZnO are also investigated by using scanning electron microscopy (SEM) images. It is seen that there are longitudinal grooves caused by micro-cutting effect and the wear mechanism is mainly abrasive in nature","PeriodicalId":207087,"journal":{"name":"International Journal of Advanced Materials Manufacturing and Characterization","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129354264","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}
