Poly-vinyl alcohol has a wide range of industrial application like textile, paper industry, food packaging industry, and as a biodegradable product like backing rolls, adhesives, coatings, surfactant etc. But hitherto, Poly-Vinyl alcohol has certain disadvantages like lower breaking elongation. Also, it is difficult to mold as it is highly viscous nature during the melting process [2]. The present research work is focused on preparation and studying the characterization of Bromelain based Poly-vinyl Alcohol fiber to improve its flexibility, thermal and mechanical characteristics. The fiber thus prepared may be employed in 3D printing application as support structures for modeling intricate shapes, production of bandages or wipes for inflammation wounds, Food packaging containers etc. For the present study, polyvinyl alcohol is tailored with Bromelain (Pineapple enzyme) which is used as an additive in this process and was analyzed in different stoichiometric ratios. Glycerin was employed as plasticizer to improve its flexibility and strength. The results that was inferred from the tests are namely: maximum tensile strength of 7.66 Mpa, maximum brake load and stress from three-point bending test was found to be 35 N and 2.593 Mpa, the temperature range shifts on addition of Bromelain was derived from TG/DTA analysis to understand its ductility, tensile strength, strength enhancement, thermal stability etc., and observation and recording of SEM images for studying its internal structure. Therefore, the tailored feedstock was tested and analyzed to understand the variation in its properties thus broadening its applications.","PeriodicalId":420098,"journal":{"name":"RECENT TRENDS IN MANUFACTURING TECHNOLOGIES, MATERIALS PROCESSING, AND TESTING","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125817233","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 significant ATIG input process parameters considered are welding current, welding speed, arc gap and gas flow rate. The quality characteristic for the depth of penetration is to be maximised while the aspect ratio (ASR) has to be minimised. The macro structure and the microstructure are captured to study the metallurgical changes that happens during the changes in the process parameters. ANOVA is performed to find the effect of significant process parameter on the response. The welding speed plays a major role in affecting the depth of penetration and the aspect ratio in multi objective optimization. The confirmation run is conducted by setting the levels of the parameter at the optimum levels to determine the optimum penetration and the aspect ratio of the joints.","PeriodicalId":420098,"journal":{"name":"RECENT TRENDS IN MANUFACTURING TECHNOLOGIES, MATERIALS PROCESSING, AND TESTING","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125556576","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 evenly distributed CNTs in the Al Matrix is the critical phenomenon in the enhancement of the properties. Through ball milling the uniform dispersion of the reinforcements is been achieved. The composites are known for the low weight, high strength, better corrosion resistant, high impact strength, enhanced stiffness and toughness which require negligible maintenance and survive for long durability. In the present work, high-energy ball milling is accomplished to disperse the MWCNTs up to 2wt% in an Al-6061 matrix. Al-CNT composite was prepared using Hydraulic press with double punch die and sintered in muffle furnace. The reinforcements were added to the base material with different wt% like0, 1, 1.5 and 2 through powder metallurgy procedure, the corrosion studies were conducted as per the Mass loss technique and using spray technique, over a period of 24hrs, 48hrs, and 72hrs. In this work the CNTs used as reinforcement with varying weight % of 1,1.5,2 and Al6061 alloy as a matrix material. The composites were fabricated through powder metallurgy route. Ball milling was done to get homogeneous dispersion of CNT’s. Samples prepared as per ASTM E9 standard for various compositions and investigated for microstructure using scanning Electron microscopy (SEM). The observations were made in the gaps of 24, 48,72hrs and obtained the mass loss data in each day. Later the corrosion rate was calculated. The corroded specimens were then analyzed using SEM. The results revealed that as the wt% of the MWCNTs was increased the Corrosion rate was found to be decreased.","PeriodicalId":420098,"journal":{"name":"RECENT TRENDS IN MANUFACTURING TECHNOLOGIES, MATERIALS PROCESSING, AND TESTING","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125694134","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 this context, PLA materials have been commonly used in the 3D printing manufacturing methodology. As the result, various studies have been carrying out by the researchers in the PLA and its properties. Despite of much work, further studies also been needed for identification of the suitable machining performances. As machining output responses also plays a crucial role over the properties of the material after manufacturing. So in this research, wood PLA have been considered and the input machining parameters for the 3D printer such as layer height, infill percentage, and infill pattern have been optimized to yield better tensile strength, tensile modulus and energy absorption rate. As part of this research, set of 27 different experiments had also been conducted to study the vital logic exist between the parameters and the responses. The effects of the printing process parameters and responses have been used to formulate the multi objective function. This multi objective function has been used as the fitness function for the optimization algorithm. Genetic algorithm has been used to optimize the 3D printer process parameters. The aim of the manuscript is to analyze the effects of input and output responses of 3D printer by experimentation, formulation of relational equation and optimization of the control parameters using genetic algorithm. Further, the developed genetic algorithm has been validated by conducting the test experiments with the optimized values. The obtained test results are comparable with the simulation results and thus concluded that the developed algorithm module can be used for the optimization of the 3D printer process parameters.","PeriodicalId":420098,"journal":{"name":"RECENT TRENDS IN MANUFACTURING TECHNOLOGIES, MATERIALS PROCESSING, AND TESTING","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124833391","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}

Corrosion can result in the of weakening of the material, rise in fires, collapse of building, breakage of pipelines, leakage in chemical plant and many more. This leads to the use of corrosive resistive materials. A nickel-based alloy names “Monel 400” is one such material which is resistive to corrosion damage over a significant period. Use of Monel 400 is primarily in the field of marine, aerospace, oil and chemical environment due to its strong toughness over a high range of temperatures, work hardening properties and corrosive resistive characteristics. As machining on Monel is relatively tough, a non-conventional machining technique called “Abrasive waterjet machining” is followed to overcome the issue. Garnet sand is used as the abrasive with the size range varying from 80 to 85 mesh. Improvement of the parameters such as surface finish and circularity error were minimized using Monel 400 along with use of response surface model, various statistical formulations like ANOVA and regression equations. It was proved that water pressure and the flow rate of abrasive were the most inducing factors in the machining process from the derived results. Finally, the surface roughness and circularity error for mesh 85 and mesh 80 were derived and compared with the influencing parameters such as water pressure and rate of abrasive flow.","PeriodicalId":420098,"journal":{"name":"RECENT TRENDS IN MANUFACTURING TECHNOLOGIES, MATERIALS PROCESSING, AND TESTING","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114688847","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}
