The Department of Mechanical and Industrial Engineering Technology, Faculty of Engineering and the Built Environment, invites you to an Expert Talk entitled: “Development In Hybrid Machining Processes: A Focus on Rotary Ultrasonic Machining and Micro-Electrochemical Machining”

Guest Speaker

Dr. Ravi Pratap Singh, Assistant Professor, Mechanical Engineering National Institute of Technology, Kurukshetra (Haryana) India.


Over the last two decades, product miniaturization with integrated functions is a recent trend in manufacturing industries due to the multiple benefits of microproducts and miniaturized featured components. With the development in MEMS, microproducts are widely used in various fields namely electronics, aerospace, optical, biomedical, automotive, etc. Different micromachining methods are available to machine the micro features on macro or micro-sized components on advanced engineering materials, which can be selected based on a number of criteria such as required machining accuracy, tolerance offered, surface finish, type of workpiece material, production rate, and cost of production. In this progressive way, Rotary Ultrasonic Machining (RUSM) and Mirco Electrochemical Machining (µECM) are feasible solutions to process the newest engineering materials with superior performance. This expert talk will shed light on developments in these two processes.


Dr Ravi Pratap Singh is presently working as Assistant Professor (Grade-I) in the Department of Mechanical Engineering at the National Institute of Technology, Kurukshetra, Haryana, India. He is a Life Member of The Institution of Engineers (India), Ultrasonic Society of India (USI), Additive Manufacturing Society of India (AMSI), and SCIence and Engineering Institute (SCIEI), Log Angeles, USA. He has published more than 150 research articles throughout the several SCI / Scopus indexed journals, including International / National level conferences. His research articles have received more than 5500 citations around the globe with the h-index of 40. Dr Singh is also working as a Principal-Investigator (PI) of SERB-GoI funded and Co-PI of ISRO-YUKTI funded projects which are in progress. He has also completed two research projects as a PI & Co-PI. He has also been granted two Indian Patents in the domain of Development of Hybrid Machining Tools and Methods. Dr. Singh has also been ranked among the top 2% of Scientists in the world as per the report by STANFORD University for the years 2021, 2022, and 2023.
