    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.
