This paper deals with the experimental investigation of effects of geometrical parameters of cutting tool insert and analysis of output responses such as surface roughness and Material Removal Rate (MRR) during machining AISI 1045 steel. This analysis is essential, since the wear, occurring at the cutting edge of the insert favors the surface roughness at the machined surface. Taguchi's Design of...
Stir cast Al 7075/20%SiCp composites were subjected to compression testing at strain rates and temperatures ranging from 0.001 to 1.0 s−1 and from 300 to 500°C respectively. The associated microstructural transformations and instability phenomena were studied by observations of the optical electron microscope. The power dissipation efficiency and instability parameter were calculated by using the...
A nine-leaf steel spring used in the rear suspension system of a light duty vehicle is analyzed by finite element method using ANSYS software. The finite element analysis results of stress and deflection are verified with the analytical solution and experimental results. It is proposed to replace the existing steel spring with composite spring. With the results of the steel leaf spring, a mono leaf...
During the past decade, the teachers in the schools have increased their use of Internet-based content and resources in their classrooms. The blended approach combines the best elements of online and face-to-face learning. Blended learning is booming as the education becomes more demand-focused. This paper briefly explains about a system which supports to educate the children in a blundered learning...
This paper presents a study of the vibro-feeder and solution for the problems which rise during its control. The control of the vibro-feeder in a simplified manner depending on the required feed rate will be discussed in addition to the new types & technologies. The paper will also present an alternate design that will replace the present Mother Card and Baby Card system. The vibro-feeder is made...
In this study, the effect of rotational speed on the microstructural changes and the mechanical properties of friction stir processed Mg AZ31B alloy sheets has been investigated. Friction stir processing was carried out at rotational speeds in the range of 900 to 1400 rpm with a constant traverse speed of 32 mm/min. The results show that the rotational speed has a significant effect on the microstructures...
In this information age, data has become one of the most important resources to organizations. The effective and efficient management of large quantities of data is a common problem found in many industries. An effective Management Information System (MIS) supplies accurate, relevant and timely information to the manager of an organization. Decision making is an important requirement in every organization,...
In future, as the size of channel length decrease, the necessity of low power based circuit will be increased. In nanometer regime, CMOS based circuits may not be used due to problem in its fundamental material, short channel effect and high leakage. To achieve low power device in nanometer region can be obtained by utilizing alternative technologies devices like FinFET. In most of the electronic...
Wire Electric Discharge Machining (WEDM) is one of the important non-traditional machining processes for machining of intricate profiles in conductive and difficult to machine materials. The machining performance of this process largely depends on various process parameters, such as applied voltage, ignition pulse current, pulse-off time, pulse duration, serve controlled reference mean voltage, servo-speed...
