I congratulate the authors Dr. P. Kannaiah, Prof. K.L. Narayana and Mr. K. Venkata Reddy of
S.V.U. College of Engineering, Tirupati for bringing out this book on “Machine Drawing”.
This book deals with the fundamentals of Engineering Drawing to begin with and the
authors introduce Machine Drawing systematically thereafter. This, in my opinion, is an excellent
approach. This book is a valuable piece to the students of Mechanical Engineering at diploma,
degree and AMIE levels.
Dr. P. Kannaiah has a rich experience of teaching this subject for about twenty five
years, and this has been well utilised to rightly reflect the treatment of the subject and the
presentation of it. Prof. K.L. Narayana, as a Professor in Mechanical Engineering and Mr. K.
Venkata Reddy as a Workshop Superintendent have wisely joined to give illustrations usefully
from their wide experience and this unique feature is a particular fortune to this book and such
opportunities perhaps might not have been available to other books.
It is quite necessary for any drawing book to follow the standards of BIS. This has been
done very meticulously by the authors. Besides, this book covers the syllabi of various Indian
universities without any omission.
Learning the draughting principles and using the same in industrial practice is essential
for any student and this book acts as a valuable guide to the students of engineering. It also
serves as a reference book in the design and draughting divisions in industries. This book acts
almost as a complete manual in Machine Drawing.
This book is a foundation to students and professionals who from here would like to learn
Computer Graphics which is a must in modern days.
I am confident that the students of engineering find this book extremely useful to them.

The engineer, especially a mechanical engineer, needs a thorough knowledge of the working
principles of any mechanism he normally deals with. To create interest and to motivate him in
this direction, complete revision of the chapter on assembly drawings is done. The chapter
provides individual component drawings and knowing the working mechanism of a subassembly,
finally the parts are assembled. Hence, exercises/examples are included starting from simple
subassemblies to moderately complex assemblies.
The chapter on part drawings provides examples of assembled drawings and the student
is expected to make the part drawings after imagining the shapes of them. A revision of this
chapter is supposed to provide the required guidance to the knowledge seeker.
The chapter on computer-aided draughting is fully revised keeping in view the present
day requirements of the engineering students. The student should be trained not only to use
draughting equipment but also to use a computer to produce his latest invention. It is pre-
sumed that this chapter will provide him the required soft skills.
The centers of excellence should revise the curriculum frequently, based on the changes
needed by the academic requirements. Keeping this in view, the contents of the text are updated
wherever necessary and incorporated.
It is hoped that the subject content satisfies both students, teachers and paper setters.

Drawing, as an art, is the picturisation of the imagination of the scene in its totality by an
individual—the Artist. It has no standard guidelines and boundaries. Engineering drawing on
the other hand is the scientific representation of an object, according to certain national and
international standards of practice. It can be understood by all, with the knowledge of basic
principles of drawing.
Machine drawing is the indispensable communicating medium employed in industries,
to furnish all the information required for the manufacture and assembly of the components of
a machine.
Industries are required to follow certain draughting standards as approved by
International Organisation for Standards (ISO). When these are followed, drawings prepared
by any one can convey the same information to all concerned, irrespective of the firm or even
the country. Mechanical engineering students are required to practice the draughting standards
in full, so that the students after their training, can adjust very well in industries.
This book on Machine Drawing is written, following the principles of drawing, as
recommended by Bureau of Indian Standards (BIS), in their standards titled “Engineering
drawing practice for schools and colleges”; SP:46-1988.
This is the only book on Machine Drawing, incorporating the latest standards published
till now and made available to the students. Typical changes brought in the standards, in respect
of names of orthographic views are listed below. These eliminate the ambiguity if any that
existed earlier.
The latest designations as recommended below are used throughout this book.
Designation of the views Designations of the views
as per IS:696-1972 as per SP:46-1988
1. Front view The view from the front
2. Top view The view from above
3. Left side view The view from the left
4. Right side view The view from the right
5. Bottom view The view from below
6. Rear view The view from the rear
The contents of the book are chosen such that, the student can learn well about the
drawing practice of most of the important mechanical engineering components and sub-
assemblies, he studies through various courses.
