FOREWORD
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.

PREFACE TO THIRD EDITION
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 presumed 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...
