Design and Development of Honeycomb Structure for Additive Manufacturing

the demand for shorter product development time has resulted in the introduction of a new paradigm called Additive Manufacturing AM . Due to its significant advantages in terms of cost effective, lesser build time, elimination of expensive tooling, design flexibility AM is finding applications in many diverse fields of the industry today. One of the recent applications of this technology is for fabrication of cellular structures. Cellular structures are designed to have material where it is needed for specific applications. Compared to solid materials, these structures can provide high strength-to-weight ratio, good energy absorption characteristics and good thermal and acoustic insulation properties to aerospace, medical and engineering products. 

However, due to inclusion of too many design variables, the design process of these structures is a challenge task. Furthermore, polymer additive manufacturing techniques, such as fused deposition modeling FDM process which shows the great capability to fabricate these structures, are still facing certain process limitations in terms of support structure requirement for certain category of cellular structures. 

Therefore, in this research, a computer-aided design CAD based method is proposed to design and develop hexagonal honeycomb structure self-supporting periodic cellular structure for FDM process. This novel methodology is found to have potential to create honeycomb cellular structures with different volume fractions successfully without any part distortion. Once designing process is complete, mechanical and microstructure properties of these structures are characterized to investigate effect of volume fraction on compressive strength of the part. 

Volume fraction can be defined as the volume percentage of the solid material inside the cellular structure and it is varied in this thesis by changing the cell size and wall thickness of honeycombs. Compression strength of the honeycomb structure is observed to increase with the increase in the volume fraction and this behavior is compared with an existing Wierzbicki expression, developed for predicting compression properties. 

Some differences are noticed in between experimentally tested and Wierzbicki model estimated compressive strength. These differences may be attributed to layer by layer deposition strategy and the residual stress inherent to the FDM-manufacturing process.

The Production of Instant Powder Fermented Soy Food Supplement Enriched with Rice Bran

Fermented soy bean or tempe has been documented as source of vegetable protein and consumed mainly by most Indonesian people living in Java Island. However due to having short storage life and also lack of vitamin and mineral become the main hindrance to develop the utilization of this product. The processing of fermented soy bean into probiotic powder supplement enriched with rice bran has been searched. Three stages of experiments were carried out. The first stage was to find out the effect of fermentation time on the characteristic and total microbial load of fermented soy bean. 

A single factor with six levels 4, 6, 8, 10, 12 and 14 hours with four replications were used to carry out this study. The second stage of experiment was to find out the effect of temperature and emulsifier concentration on the characteristic and storage life of the fermented powder food supplement. A randomize block design was used to carried out this study. 

The temperature at three levels 50, 55 and 60ºC as the first factor and emulsifier tween 80 concentration at two levels 0.3 and 0.4 w w as the second factor, all the treatments were repeated three times. Result from the first stage shown that the fermentation time of 12 hours has the highest total microbial load of 0.8x108 cells ml while the protein content was 2.894 w w, fat content 1.2209 w w, pH 3.6 and the ash content of 0.57 w w. 

Result from the second stage shown that the temperature of 500C and tween 80 at a concentration level of 0.3 w w, has total microbe of 0.24x108 cells ml and 282.67 mg 100 g isoflavone. The powder enriched with rice bran has a significant role to increase the body weight of rats. After 15 days of feeding the rats body weight increased about 30 w w.

Investigation on Mechanical Properties of AL6061 Alloy Processed by FSW

The aim of this experiment was to improve the mechanical properties of 6061 aluminium alloys by friction stir processing FSP , a solid-state technique for micro structural modification using the heat from a friction and stirring. The Aluminium alloy 6061 is widely used in the fabrication of lightweight structures with high strength-to-weight ratio and good corrosion resistance. Welding is main fabrication method of 6061 alloy for manufacturing various engineering components. Friction stir welding FSW is a recently developed solid state welding process to overcome the problems encountered in fusion welding. 

This process uses a non-consumable tool to generate frictional heat on the abutting surfaces. The welding parameters, such as tool pin profile, rotational speed, welding speed and axial force, play major role in determining the micro structure and corrosion resistance of welded joint. In this work a central composite design with two different speeds, traverse speeds and Four tools has been used to minimize the experimental conditions.

Crack and Object Detection in Pipeline using Inspection Robot

Pipelines are important means of transportation of gas, water, fuel oils, etc. in various fields. The transportation loss occurs due to aging, corrosion, obstacles, crack and mechanical faults in the pipeline. The lifetime of pipeline can be increased by regular inspection of pipeline and recognizing the cracks, damages and faults in the pipeline and ensuring proper maintenance of faults. This helps in preventing transportation loss and maintaining profitable gross. Thus, this paper aims to propose an autonomous robot used for in-pipe inspection which provides easy way of detecting crack and obstacle inside the pipe. 

The mechanical model of the pipe inspection robot was design according to the requirements of physical size of the pipe. The basic design of inspection robot consists of robot body and DC motors with the rating of 9V and 35 rpm are attached to the wheels to move the robot forward and backward. The electronic circuit is developed, consisting of an H Bridge and Arduino Uno which in turn controls the entire connection of DC motors and sensors. The robot allows for detection of cracks and obstacles inside the pipe and also allows us to communicate with it through serial communication.

Automated Biometric-EVM Implemented Using Lab-View

Election commission still uses manual system during election for vote casting in this modern age of digitalization. In parliamentary elections it is consider introducing Electronic voting machines EVM though Evm is not entirely automated and has many limitations. Integrated database system containing all voters' information and a convenient user interface of an automated biometric voting system had designed, in this work. Automatically casted votes will be counted simultaneously of the voting process and result will be displayed. Using Lab VIEW enables the data base storage and file management process to easy to build and applicable in all other fields compare to other methods.

Lab VIEW is mainly for data acquisition, data base storage, extraction of the data from data base and displaying it and also for report generation to store election voting information in files for future purpose. Main advantage of this project is not using internet connection for database extraction and storing purpose. 

This paper presents 2nd stage of verification by proving Aadhar information of the voter extracted by the use of fingerprints and that going to display on screen. The Aadhar information can be monitored. In future IOT can be implemented to send election report etc. Therefore, voting management of the election commission will be improved by ceasing fraudulent activities, corruptions, ensuring security, transparency, fairness, accuracy, trustworthy and keeping backup trails of voting system can be seen in this paper.
