Machine Drawing

This well-known text book gives complete knowledge on the subject of Machine Drawing, Mechanical Drafting and Production Drawing. It follows (i) the metric system of length measurement and (ii) first-angle method of orthographic projection. However, the third-angle projection method has not been completely ignored. This Fiftieth Edition is thoroughly revised and extensively enlarged. Numerous new drawings and text matter have been incorporated to optimise the utility of the book. The chapter on Engine Parts are divided in two separate chapters such as (1) Steam Engine Parts and (2) Internal Combustion (I.C.) Engine Parts. Chapter on Computer Aided Drafting (CADr) is entirely rewritten with 52 self-interactive and self-learning practice modules. It describes in an easy-to-follow style and with application of the principles of orthographic projection, forms, proportions and uses of simple machine parts, engine parts and boiler parts. The techniques of freehand sketching, dimensioning, conversion of pictorial views, sectional views and interpretation of views are treated in clear and simple manner. Most of the orthographic views are accompanied by the pictorial views of the objects to enable the students to visualize the shapes easily.
