...Ming C. LEU Additive manufacturing: technology, applications and research needs © Higher Education Press and Springer-Verlag Berlin Heidelberg 2013 Abstract Additive manufacturing (AM) technology has been researched and developed for more than 20 years. Rather than removing materials, AM processes make three-dimensional parts directly from CAD models by adding materials layer by layer, offering the beneficial ability to build parts with geometric and material complexities that could not be produced by subtractive manufacturing processes. Through intensive research over the past two decades, significant progress has been made in the development and commercialization of new and innovative AM processes, as well as numerous practical applications in aerospace, automotive, biomedical, energy and other fields. This paper reviews the main processes, materials and applications of the current AM technology and presents future research needs for this technology. Keywords additive manufacturing (AM), AM processes, AM materials, AM applications 1 Introduction The ASTM F42 Technical Committee defines additive manufacturing (AM) as the “process of joining materials to make objects from three-dimensional (3D) model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies” [1]. It is also known as additive fabrication, additive processes, direct digital manufacturing, rapid prototyping, rapid manufacturing, layer manufacturing and solid freeform fabrication...

...Challenges for high tech development in India Inadequate Number & Frequency of Experimentation and Testing cycles While complex products are today largely designed on the computer (the Boeing 777, for example, was designed predominantly based on simulation through CAD/CAE), some amount of physical prototyping and testing is always required. Rapid testing, using low cost mock-ups and prototypes, wherever possible, is critical to completing the project quickly. But, design of complex systems in India is undermined by inadequate resources for experimentation and testing. This results in overly long development cycles. Design/Development & Production Gap After independence, India adopted the Soviet model of separation of design and development from production. As a result, we have a huge network of government owned and operated research and development laboratories and facilities, and a separate network of production units/factories (like the ordnance factories in the case of defence). The separation between R&D and manufacturing has worked to our disadvantage in multiple sectors. Take the case of telecom, where the Centre for Development of Telematics (CDOT) set up in the 1980s created contemporary digital exchanges that were well suited to the hot and dusty conditions of India and the then prevalent high number of “Busy Hour Calling Attempts.” But as I documented in From Jugaad to Systematic Innovation: The Challenge for India, the separation of the technology...

The main objective of the proposal was to analyze the operations of the Inventory Management system that is currently in use and come up with some its weaknesses and strengths. An integration of both would then enable the department to come up with a conclusion of a completely different system that would cover up for the shortcomings of the current system and add more value to its strengths. According to the proposal approved by the IT management Board, the proposed system would take at least three months to complete before implementation is done. The whole project would cost $1,500,000 to complete and implement. Some of the limitations as per the proposal included lack of enough capacity within the current PCs in use to accommodate the new system and so an upgrade to all the PCs was suggested. The user level of information was also to be upgraded to enable them use the new system effectively. The purpose of this letter is to request your office to consider the viability of this project in...

... Reverse Engineering a New Trend in Manufacturing [pic] Authors T.Dhamotharakumar* N.S.Ramesh* dhamotharan007@gmail.com nsrmechanical@gmail.com * Under graduate Student, K.S.R. College of Engineering, Tiruchengode Department of Mechanical Engineering [pic] Abstract With the significant capital investment in new equipment being placed into out years, more systems need to be maintained in their present condition for longer periods of time. There are often gaps in the technical support information needed to maintain a system built from older designs using outmoded or updated techniques or materials. In some situations, designers give a shape to their ideas by using clay, plaster, wood, or foam rubber, but a CAD model is needed to enable the manufacturing of the part. As products become more organic in shape, designing in CAD may be challenging or impossible. There is no guarantee that the CAD model will be acceptably close to the sculpted model. Reverse engineering provides a solution to this problem because the physical model is the source of information for the CAD model. This is also referred to as the part-to-CAD process. "Reverse Engineering is the process of taking a finished product and reconstructing design data in a format from which new parts or molds can be produced."-The Society of Manufacturing Engineers Key Words: Reverse Engineering, CAD, Modeling and manufacturing.

Schilling Copyright © 2009 - The McGraw-Hill Companies srl CHAPTER 1 The Importance of Technological Innovation SYNOPSIS OF CHAPTER The purpose of this chapter is to set the stage for the course by establishing the importance of managing technological innovation strategically. First the chapter overviews the importance of technological innovation for a firm’s competitive success and the advancement of society in general. The chapter points out that 1) many firms are relying on products developed in the previous three to five years for large portions of their sales and profits; 2) globalization has increased competition putting more pressure on firms to compete through innovation; 3) advances in information technology have enabled both process improvements and the efficient generation of product variants which facilitates the execution of a differentiation strategy at a reasonable cost; and that 3) the residual growth in the GDP can be attributed to technological change. Both the positive and negative effects of technological innovation are described. Advances in food production are an example of the first and pollution is an example of the latter. Next the innovation funnel is introduced to show students that on average 3,000 raw ideas must enter the funnel in order to arrive at 1 successful new product launch.

...Can you run your company out of your pocket? Discuss how smart phones, tablets, and other mobile devices can be used in running a business. Consider all types of devices With increase in the technology of smart phones, tablets and other mobile devices, the people are going more mobile. With use of smart phones, everybody is accessing their email accounts and contacts. With the use of some remote access tools, we should be able to access our desktop remotely in our mobile device and access from anywhere. Even for the accounting, the QuickBooks apps generated by intuit would help in maintaining the book. Even the payroll of the company can also be done using mobile devices. The major disadvantage would be the security, because if we lose the mobile devices, there is more chance for somebody to easily hack the information. The term cloud computing stems from the conceptual way the Internet is drawn, specifically as a cloud. Cloud computing is a way of explaining that users are no longer constrained or aware of where the services they are using reside. Both application and databases are moving from being hosted by the particular company to being outsourced to companies that can take entire enterprise applications and make them available to users via a browser.

...Op 300 Team Members: Abby Khan, Ertugrul Caglayan, Duy Bui Application of Enterprise Resource Planning (ERP) ERP (Enterprise resource planning) is a software that allows companies to automate and integrate many of their business processes, share a common database and business practices throughout the enterprise, and produce information in real time. The objective of ERP system is that it supports the streaming and distribution of geographically scattered enterprise information across all the functional units of a business house. It provides the business management executives with a comprehensive overview of the complete business process, which in turn influences their decisions in a productive way. Many big companies have adopted ERP into ways that they run business. Oracle was one of the pioneers who custom built ERP systems for many companies around the world. Omental and Cisco were one of the first companies and pioneers who had custom built ERP system installed by Oracle. The staff had to be trained to use the system, with the help of Oracle and watch it launch off after many trial and errors along the way. Jinyang a small size Korean company chose ComputerMate, a small software company in Korean, to provide and build them there ERP system.
