An Introduction to Machine Drawing and Design by David Allan Low Pdf
Excerpt from An Introduction to Machine Drawing and Design It is now generally recognised that the old-fashioned method of teaching machine drawing is very unsatisfactory. In teaching by this method an undimensioned scale drawing, often of a very elaborate description, is placed before the student, who is required to copy it. Very often the student succeeds in making a good copy of the drawing placed before him without learning very much about the object represented by it, and this state of matters is sometimes not much improved by the presence of the teacher, who is often simply an art master, knowing nothing about machine design. It is related of one school that a pupil, after making a copy of a particular drawing, had a discussion with his teacher as to whether the object represented was a sewing machine or an electrical machine. Evidently the publisher of the drawing example in this case did not adopt the precaution which a backward student used at an examination in machine design : he put on a full title above his drawing, for the information of his examiner. Now, if machine drawing is to be of practical use to any one, he must be able to understand the form and arrangement of the parts of a machine from an inspection of suitable drawings of them without seeing the parts themselves. Also he ought to be able to make suitable drawings of a machine or parts of a machine from the machine or the parts themselves.

FUNDAMENTALS OF MACHINE DRAWING by SADHU SINGH,P. L. SAH Pdf
This richly illustrated textbook, now in its Second Edition, continues to provide a solid fundamental treatment of the essential concepts of machine drawing. The book is suitable for students pursuing courses in mechanical engineering (and its related branches) both at the undergraduate degree and diploma levels. The students are first introduced to the standards and conventions of basic engineering drawing. The machine elements such as fasteners, bearings, couplings, shafts and pulleys, pipes and pipe joints are discussed in depth before moving on to detailed drawings of components of steam engines, IC engines, boilers, and machine tools. Gears are covered in a separate chapter. Finally, the book introduces the students to the principles of computer-aided drafting and designing (CADD) to prepare them to use software tools effectively for the production of computerised accurate drawings. This Second Edition includes three new chapters, namely Fits and Tolerances, Assembly Drawings, and Freehand Sketching, anda revamped chapter on Gears. Besides,all the earlier chapters have been revised and enlarged with numerous new topics and worked-out examples. Key Features Provides first and third angle projections Follows the standards set by the Bureau of Indian Standards as per IS:696–1972/SP:46–1988 Contains multiple-choice questions and practice exercises
This book provides a detailed study of technical drawing and machine design to acquaint students with the design, drafting, manufacture, assembly of machines and their components. The book explains the principles and methodology of converting three-dimensional engineering objects into orthographic views drawn on two-dimensional planes. It describes various types of sectional views which are adopted in machine drawing as well as simple machine components such as keys, cotters, threaded fasteners, pipe joints, welded joints, and riveted joints. The book also illustrates the principles of limits, fits and tolerances and discusses geometrical tolerances and surface textures with the help of worked-out examples. Besides, it describes assembly methods and drafting of power transmission units and various mechanical machine parts of machine tools, jigs and fixtures, engines, valves, etc. Finally, the text introduces computer aided drafting (CAD) to give students a good start on professional drawing procedure using computer. KEY FEATURES : Follows the International Standard Organization (ISO) code of practice for drawing. Includes a large number of dimensioned illustrations and worked-out examples to explain the design and drafting process of various machines and their components. Contains chapter-end exercises to help students develop their design and drawing skills. This book is designed for degree and diploma students of mechanical, production, automobile, industrial and chemical engineering. It is also useful for mechanical draftsmen and designers.
Machine Drawing and Design for Beginners by Henry J. Spooner Pdf
Excerpt from Machine Drawing and Design for Beginners: An Introductory Work for the Use of Technical Students It is not usual for writers to refer to such minor details as machine and lever handles, so that young draughtsmen are often left to their own resources to guide them in such matters, therefore a chapter (xiii.) dealing with them has been included. In recent years much attention has been given to roller and ball bearings, particularly in motor-car work: so the construction of these, and the principles which govern their design, are explained in Chapter XVIII. In Chapter XIX. The recent and important improvements in spur gearing are described, and although the greatly improved helical gears have made mortise wheels practically obsolete, the consideration that we shall for some years to come still be using some of the old plants led the Author to include mortise wheels in this chapter. In Chapter XXVI. Will be found over one hundred questions relating to the subject, suitable for examinations or for home work purposes.

A Manual of Machine Drawing and Design by David Allan Low Pdf
Excerpt from A Manual of Machine Drawing and Design In this work the authors have attempted to provide: - (1.) A large number of dimensioned illustrations which may serve as good drawing examples for students, examples ranging in difficulty from the simplest machine detail to a set of triple-expansion marine engines. (2.) Illustrations and descriptions of a great variety of machine details, which may assist the designer in selecting the form of detail best suited to his purpose. (3.) Many rules and tables of proportions, based on scientific principles or on numerous examples from actual practice, which may be useful to the experienced designer for the sake of comparison with the results of his own practice, and which may, to some extent at least, take the place of the well-filled notebook and collection of designs usually possessed by the experienced designer, but which the young engineer or draughtsman can scarcely be expected to have. (4.) Numerous examples showing the application of the principles of mechanics to the calculation of the proportions of parts of machines. The illustrations given are very numerous, and they have all been specially prepared for this work from working drawings, and the authors have been at great trouble to obtain examples representing the best modern practice in machine design. The authors would here acknowledge their great indebtedness to the many engineers and engineering firms throughout the country who have generously given them drawings and much valuable information, which they feel sure will prove useful to students, draughtsmen, and engineers. They would also record their indebtedness to the leading engineering papers, and to the published Proceedings of the various engineering societies, English and American, for particulars of examples of modern practice, which they have either incorporated directly, or have made use of in drawing up the numerous rules and tables which occur throughout the work. In the introductory chapter, besides several brief articles on drawing appliances and the making of working drawings, there is a collection of problems in practical geometry which are very often required in machine drawing; but the student must not imagine that the amount of geometry there given is all that he will require; in fact, as machine drawing is simply the application of practical geometry to the representation of machines, it is evident that a thorough knowledge of the latter subject will be of immense advantage in the study and practice of the former.
