ACKNOWLEDGMENT
A scholarly and quality work like designing of any seminar can be accomplished by
motivation, guidance and inspiration of certain quarters besides the individual efforts. Let
me in this page express my heartiest gratitude to all those who helped me in various
stages of this study.
I am very much thankful to Mr. Vinay Singh Marval, Head of Department (ME) for
giving me the permission to undergo this seminar and providing all the necessary
facilities.
During my seminar period all the staff members of department have helped us with their
skills. Here by I express our sincere thanks to my guide Mr. Yudhistir Saini whose
valuable guidance and kind cooperation, without which this seminar would have not been
possible.
ABSTRACT
Most of the machining processes are involved with removal of chips using traditional
machining techniques like turning, drilling, milling, grinding, etc. However, there are
situations where these processes are not satisfactory, economical or even possible. If the
work material is very hard or too flexible, shape of the part is complex or the requirement
of accuracy and surface finish is high, traditional machining techniques are not
appropriate in those cases, but nontraditional machining techniques can be applied
successfully. Now a days nontraditional machining techniques are being widely used in
many of the modern industries like automotive industries, aerospace industries, electronic
industries and others.

INTRODUCTION
Manufacturing processes can be broadly divided into two groups and they are primary
manufacturing processes and secondary manufacturing processes. The former ones
provide basic shape and size to the material as per designer’s requirement. Casting,
forming, powder metallurgy are such processes to name a few. Secondary manufacturing
processes provide the final shape and size with tighter control on dimension, surface
characteristics etc. Material removal processes are mainly the secondary manufacturing
processes.
Material removal processes once again can be divided into mainly two groups and they
are “Traditional Machining Processes” and “Non-Traditional Manufacturing Processes”.
Examples of traditional machining processes are turning, boring, milling, shaping,
broaching, slotting, grinding etc. Similarly, Abrasive Jet Machining (AJM), Ultrasonic
Machining (USM), Water Jet and Abrasive Water Jet Machining (WJM and AWJM),
Electro-discharge Machining (EDM) are some of the Non Traditional Machining (NTM)
Processes.

LITERATURE SURVEY
A literature review is part of a research project where a researcher researches on similar
work to his or hers. This very important part of the research helps the researcher to find
out how other researchers have tackled the problem he/she is attempting to solve. It gives
insight on how to go about solving the problem at hand and provides information on
available technologies and tools for solving the problem.
Traditional machining, one of the most important material removal methods, is a
collection of material-working processes in which power-driven machine tools, such as
saws, lathes, milling machines, and drill presses, are used with a sharp cutting tool to
mechanically cut the material to achieve the desired geometry. Machining is a part of the
manufacture of almost all metal products, and it is common for other materials, such as
wood and plastic, to be machined. A person who specializes in machining is called a
machinist. A room, building, or company where machining is done is called a machine
shop. Much of modern day machining is controlled by computers using computer
numerical control (CNC) machining. Machining can be a business, a hobby, or both.
The precise meaning of the term "machining" has evolved over the past 1.5 centuries as
technology has advanced. During the Machine Age, it referred to (what we today might
call) the "traditional" machining processes, such as turning, boring, drilling, milling,
broaching, sawing, shaping, planning, reaming, and tapping, or sometimes to grinding.
Since the advent of new technologies such as electrical discharge machining,
electrochemical machining, electron beam machining, photochemical machining, and
ultrasonic machining, the retronym "traditional machining" can be used to differentiate
the classic technologies from the newer ones. The term "machining" without qualification
