Mechanics Of Machining

By Prof. Uday S. Dixit   |   IIT Guwahati
Learners enrolled: 504   |  Exam registration: 135
ABOUT THE COURSE : Machining is a metal removal process, which can be accomplished by applying force on raw material by means of a cutting tool. This course aims at explaining the physics of the cutting process. The course will contain discussion of statics, kinematics and kinetics of the cutting process. Experimental findings relevant to mechanics of the process will also be discussed. The course will also include introductory discussion on non-traditional machining processes.

Instructor bio

Prof. Uday S. Dixit

IIT Guwahati
Dr. Uday Shanker Dixit is presently Professor in the Department of Mechanical Engineering and Head of Center for Indian Knowledge System at Indian Institute of Technology Guwahati. He received B.E. degree in Mechanical Engineering from erstwhile University of Roorkee (now Indian Institute of Technology Roorkee) in 1987, M.Tech. degree in Mechanical Engineering from Indian Institute of Technology Kanpur in 1993, and Ph.D. in Mechanical Engineering from 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 the Officiating Director of Central Institute of Technology, Kokrajhar from February 2014 to May 2015. Dr. Dixit is actively engaged in the research in various areas of design and manufacturing since last three decades. Most of his research work is focused on Modelling of Manufacturing Processes and involves finite element analysis and soft computing. He has also contributed in design optimization. He has extensively used finite element and soft computing tools for the design and manufacture of mechatronic systems. He has authored/co-authored about 170 journal papers, 166 conference papers, 48 book chapters and 9 books in mechanical engineering. He has also co- edited 11 books and several conference proceedings. He has guest-edited 11 special issues of journals. Presently he is an Associate Editor of the Journal of Institution of Engineers (India), Series C, Regional Editor Asia of International Journal of Mechatronics and Manufacturing Systems and Associate Editor of Journal of Micromanufacturing. He has guided 21 doctoral and 60 masters’ students. Dr. Dixit has investigated a number of sponsored projects and developed several courses. He is a Fellow of Indian Welding Society, National Advisory Committee member of International & All India Manufacturing, Technology and Design Conference. He was a Board Member of Indian Institute of Technology Kanpur from 2018 to 2021. He is a reviewer of several journals and has organized several conferences. He has international collaboration with several researchers. He has executed several socially relevant projects, such as technology development to upgrade the skills of brass metal artisans of Hajo, Guwahati and development of machine for making plates out of areca nut. He has also mentored some startups.
