...productivity and machining quality 3 Conventional motor technology suffers from major drawbacks 3 Benefits of synchronous spindles 4 Thinking out of the box and engineering bespoke solutions can pay beyond expectations 8 Innovation as a powerful mean of differentiation 9 An unprecedented recession Since the downturn in 2008, the machine tools industry, like many other manufacturing industries, has suffered from an unprecedented crisis which has shaken the strongest companies, not only in Europe and the USA but also Asia. Machine tools OEMs (Original Equipment Manufacturers) saw their sales plummet by up to 65% in the wake of the decline of their customer markets, such as automobile manufacturing. The crisis, made worse by the decline in lending, effectively stopped all capital investment over the last couple of years. With such low turnovers, none of the classical cost reduction measures like short time working, inventory reduction and efficiency measures was enough to avoid negative earnings. In contrast, the traditional industry challenges of improved machining quality, reduced machine costs and improved end user operating costs still demand addressing. In such a challenging environment, the panacea could come from innovative solutions devised and developed by ever more creative companies. This paper presents some of those innovations. Improved thermal stability of new motor technology raises spindle productivity and machining quality Machining quality is...

...[pic] 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. ...

...The history and evolution of materials used to make automotive engine blocks The engine is an essential part of an automobile that provides tractive force to drive the entire vehicle. Most of the current engines are the integral section of a vehicle which is built in different arrangements and more complex as compared to the early engines. The common parts present in an engine include camshaft, rocker arms, pistons, crankshaft, flywheel, both oil and fuel pumps and other various components. The discovery of both light, as well as stronger engineering materials in manufacturing different parts of an engine, has had an impact on power to weight of the engine thus making the entire automobile very light. An engine block or else cylinder block is the base of an engine that accommodates about all the parts needed for an engine to perform properly. There exist mainly three configurations of an engine block, that is, horizontally-opposed, “V”- shaped as well as inline configurations. The number of cylinders within these block configurations varies from a minimum of two to a maximum of sixteen depending on the power needed. Since an engine block is the most significant part of an engine, it should satisfy quite many functional requirements. The functional requirements include; 1. Housing of the moving components and the fluids, 2. Enduring the varying thermal pressures generated during combustion process, 3. Making the automobile last longer, 4. Maintaining of the engine...

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...
