TABLE OF CONTENTS This book is a foundational book for manufacturing engineering students studying the topic of engineering drawing. Engineering drawing is important to manufacturing engineers because they are invariably at the receiving end of a drawing. Designers come up with the overall from and layout of an artefact that will eventually be made. This is the basic object of engineering drawing to communicate product design and manufacturing information in a reliable and unambiguous manner.
Nowadays, companies operate over several continents. Engineering drawings need to be language-independent so that a designer in one country can specify a product which is then made in another country and probably assembled in yet another. Thus, engineering drawing can be described as a language in its own right because it is transmitting information from the head of the designer to the head of the manufacturer and indeed, the head of the assembler. This is the function of any language. The rules of a language are defined by grammar and spelling. These in turn are defined in grammar books and dictionaries. The language of engineering must be similarly defined by rules that are embodied in the publications of standards organisations. Each country has its own standards organisation. For example, in the UK it is the British Standards Institution (BSI), in the USA it is the American National Standards Institute (ANSI) and in Germany it is the Deutsches Institut f r Normung (DIN). However, the most important one is the International Standards Organisation (ISO), because it is...
