Mechanics of Machining

By Prof. Uday S. Dixit   |   IIT Guwahati
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.


INTENDED AUDIENCE : UG and PG students of Mechanical/Production/Manufacturing

    INSTRUCTOR BIO

    Prof. Uday S. Dixit

    IIT Guwahati
    Dr. Uday Shanker Dixit 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 research in various areas of design and manufacturing since last about 30 years. Most of his research work is focused on Modelling of Manufacturing Processes and involves finite element analysis of elastoplastic problems. He has authored/co-authored 118 journal papers, 111 conference papers, 31 book chapters and 7 books in mechanical engineering. He has also co-edited 7 books related to manufacturing. 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 and Regional Editor Asia of International Journal of Mechatronics and Manufacturing Systems. He has guided 12 doctoral and 44 masters’ students. Dr. Dixit has investigated a number of sponsored projects and developed several courses including a NPTEL course on Engineering Mechanics.
