Application of Lasers in Manufacturing Select Papers from AIMTDR 2016

This book mainly addresses the applications of lasers in the manufacture of various industrial components. The technologies presented here have scopes of application ranging from the macro to meso and micro level of components and features. This book includes chapters on the basic and advanced applications of lasers in the manufacturing domain. They present theoretical and practical aspects of laser technology for various applications such as laser-based machining, micro-scribing, texturing, machining of micro-sized channels; laser welding; laser-based correction of sheet metal, i.e. straightening; laser forming; and laser technology for 3-D printing. Lasers have various applications such as the production of powerful lights for illumination or decoration; measurement of velocity (transportation) and length; interferometry; printing; recording; communication; bio-medical instrumentation and pollution detection. A significant body of literature is available on the physics of lasers and types of lasers. However it has been noted there are a few books published on the “applications of lasers in manufacturing domain,” a gap that this book remedies. Gathering contributions by leading engineers and academicians in this area, it offers a valuable source of information for young scientists and research students.

Dr. Uday Shanker Dixit received his B.E. degree in Mechanical Engineering from the erstwhile University of Roorkee (now the Indian Institute of Technology Roorkee) in 1987, his M.Tech. degree in Mechanical Engineering from the Indian Institute of Technology Kanpur in 1993, and his Ph.D. in Mechanical Engineering from the IIT Kanpur in 1998. He has worked in two industries—HMT, Pinjore and INDOMAG Steel Technology, New Delhi, where his main responsibility was designing various machines. Dr. Dixit joined the Department of Mechanical Engineering, Indian Institute of Technology Guwahati, in 1998, where he is currently a professor. He was also Officiating Director of the Central Institute of Technology, Kokrajhar from February 2014 to May 2015. Dr. Dixit has been actively engaged in research in various areas of design and manufacturing for the past 25 years. He has authored/co-authored 75 journal papers, 91 conference papers, 20 book chapters and 6 books on mechanical engineering. He has also co-edited 3 books related to manufacturing. Out of these 9 books, 6 have been published by Springer. He has guest-edited 10 special issues for journals and is currently an associated editor of the Journal of Institution of Engineers (India), Series C.

Dr. Joshi received his Ph.D. in "Intelligent process modeling and optimization of electric discharge machining" from the Indian Institute of Technology (IIT) Bombay, India in 2010. Currently, he is working as an Associate Professor at the Department of Mechanical Engineering, Indian Institute of Technology (IIT) Guwahati, India. His research interests include laser-based manufacturing, ultra-precision machining, computer-aided design and manufacturing (CAD/CAM), and manufacturing process modeling & optimization. Dr. Joshi has published about 45 papers in journals and conferences of national/international repute, and has edited a book on "Laser-based manufacturing" (Springer) along with Prof. U. S. Dixit, IIT Guwahati. He has also authored four book chapters in books published at the international level.

Dr. J. Paulo Davim received his Ph.D. in Mechanical Engineering from the University of Porto in 1997, the Aggregate title from the University of Coimbra in 2005, and a DSc from London Metropolitan University in 2013. Currently, he is a professor at the Department of Mechanical Engineering of the University of Aveiro. He has over 30 years of teaching and research experience in manufacturing, materials, and mechanical engineering with a special focus on machining and tribology.  He has also started taking an interest in management/industrial engineering and higher education for sustainability. He has worked as an evaluator of projects for international research agencies as well as an examiner of Ph.D. thesis for many universities. He is the editor-in-chief of several international journals, guest editor of journals, book editor, book series editor, and scientific advisory for many international journals and conferences. Presently, he is an editorial board member of 25 international journals and serves as reviewer for more than 80 prestigious Web of Science journals. In addition, he has also published, as author and co-author, more than 10 books, 80 book chapters, and 400 articles in journals and for conferences.
