Mass, motion, forces, energy, design, and manufacturing—these comprise the world of mechanical engineering today. Continual research and development has led to better machines and processes culminating in key events and technological advancements, that have improved the 'quality of life' of mankind. Mechanical engineering is concerned with all aspects—design, development, construction, production, installation, operation and maintenance—of almost everything that we come across in our daily lives-be it a sophisticated jet engine or a simple toy. It is to acknowledge the growing importance of this field IUP has come up with a quarterly journal—The IUP Journal of Mechanical Engineering.

A Comparison of TiCN + Al2O3 + TiN and TiAlN Coated Carbide Tools for Machining of Inconel 718

--S N Shinde, D S Jadhav, K S Hirpara, K K Chaute and J H Vithalani

The increasing demand for quiet power transmission in machines, vehicles and generators has The paper aims at investigating the effect of cutting speed, feed rate and depth of cut on surface roughness and temperature generation at tool work interface. It also aims at investigating the cutting force and thrust force for different cutting speeds and feed rates for same depth of cut in dry turning of Inconel 718. It compares the performance of tools TiCN + Al2O3 + TiN and TiAlN coated carbide tool in dry turning of Inconel 718 and finds the optimum tool for machining of Inconel 718.

AA6061/B4C/Graphite/CeO2 Reinforced Hybrid Composite Development and Evaluation of Its Properties

--Pardeep Sharma, Krishan Paliwal, Dinesh Khanduja, Vishal Dabra and Rahul Saini

The paper focuses on the development of AA6061 single reinforced composites with 5 wt.% of graphite, 5 wt.% of boron carbide and a hybrid composite reinforced with 5 wt.% graphite + 5 wt.% boron carbide + 5 wt.% cerium oxide. The microstructures of manufactured single reinforced composite and hybrid composite were studied using optical microscope. The mechanical properties like hardness and tensile strength were also studied. The Vickers microhardness of graphite reinforced composites decreased from 45 VHN to 36 VHN and of boron carbide reinforced composites increased from 45 VHN to 74 VHN, while that of hybrid composites increased from 45 VHN to 68 VHN. The Brinell macrohardness of graphite reinforced composites decreased from 30 BHN to 25 BHN and of boron carbide reinforced composites increased from 30 BHN to 50 BHN, while that of hybrid composites increased from 30 BHN to 44 BHN. The ultimate tensile strength of graphite reinforced composites decreased from 160 MPa to 138 MPa and of boron carbide reinforced composites increased from 160 MPa to 195 MPa, while that of hybrid composite increased from 160 MPa to 175 MPa.

Some Models of Surface Treatment by Laser Melting

--Rahul Basu

Moving heat sources of laser melting are treated with various transformations along with a decoupling for the heat and mass transfer terms. The scale for heat diffusion is different from conduction, and when small intervals of time are involved in rapid solidification, the effect may be pronounced. Very little published work exists on the stability of the solid-liquid interface. It is essential to understand this aspect because instabilities in solidification processes will affect the final finish of the surface. Novel transforms specific to melting with convective surface conditions are applied to this analysis. Phase field theory notions are applied to specific cases for amorphous film formation.

3D Metal Printing Technologies: A Review

--Avinash Malladi and SBS Sarma

3D printing is a branch under additive manufacturing, where converting the design to manufacturing model is done. Breaking the boundaries of traditional manufacturing process of complex structures, 3D printing has helped the industrial designers by enabling the design components based on functionality. The researchers are extending their research in identifying the new technologies in 3D printing to their full potential with respect to materials and process specialization for industrial end users. This paper provides information on various industry-based 3D printing technologies and also presents a comparison of them.

Prediction of Interfacial Tension of Fish Oil Silver Nitrate Binary System by Spinning Drop Tensiometry

--Kirubanandan Shanmugam

The Interfacial Tension (IFT) of an immiscible binary system is the most important property in the process design of Liquid-Liquid Extraction (LLE) and also in numerous mass transfer operations. Recently, the extraction of omega 3 Poly Unsaturated Fatty Acids (PUFA) from fish oil with silver nitrate solution is a novel extraction process, and in this case of process design, there is a lack of details about physical properties of fish oil silver nitrate system. Fish oil Ethyl Ester (EE)-AgNO3 is a rare binary system which lacks information about IFT system details. This work thus explored the interfacial surface force variations with practical fish oil/solvent/silver nitrate mixtures using spinning drop tensiometer to explore the observed variation in the flow pattern. The IFT data is used to design the flow dynamics of the extraction process design at mini/micro scale flow reactors.

Automated Teller Machines (ATMs): The Changing Face of Banking in India

Bank Management
Information and communication technology has changed the way in which banks provide services to its customers. These days the customers are able to perform their routine banking transactions without even entering the bank premises. ATM is one such development in recent years, which provides remote banking services all over the world, including India. This paper analyzes the development of this self-service banking in India based on the secondary data.

The Information and Communication Technology (ICT) is playing a very important role in the progress and advancement in almost all walks of life. The deregulated environment has provided an opportunity to restructure the means and methods of delivery of services in many areas, including the banking sector. The ICT has been a focused issue in the past two decades in Indian banking. In fact, ICTs are enabling the banks to change the way in which they are functioning. Improved customer service has become very important for the very survival and growth of banking sector in the reforms era. The technological advancements, deregulations, and intense competition due to the entry of private sector and foreign banks have altered the face of banking from one of mere intermediation to one of provider of quick, efficient and customer-friendly services. With the introduction and adoption of ICT in the banking sector, the customers are fast moving away from the traditional branch banking system to the convenient and comfort of virtual banking. The most important virtual banking services are phone banking, mobile banking, Internet banking and ATM banking. These electronic channels have enhanced the delivery of banking services accurately and efficiently to the customers. The ATMs are an important part of a bank’s alternative channel to reach the customers, to showcase products and services and to create brand awareness. This is reflected in the increase in the number of ATMs all over the world. ATM is one of the most widely used remote banking services all over the world, including India. This paper analyzes the growth of ATMs of different bank groups in India.
International Scenario

If ATMs are largely available over geographically dispersed areas, the benefit from using an ATM will increase as customers will be able to access their bank accounts from any geographic location. This would imply that the value of an ATM network increases with the number of available ATM locations, and the value of a bank network to a customer will be determined in part by the final network size of the banking system. The statistical information on the growth of branches and ATM network in select countries.

Indian Scenario

The financial services industry in India has witnessed a phenomenal growth, diversification and specialization since the initiation of financial sector reforms in 1991. Greater customer orientation is the only way to retain customer loyalty and withstand competition in the liberalized world. In a market-driven strategy of development, customer preference is of paramount importance in any economy. Gone are the days when customers used to come to the doorsteps of banks. Now the banks are required to chase the customers; only those banks which are customercentric and extremely focused on the needs of their clients can succeed in their business today.
