Blueprint Reading for the Machine Trades (4th Edition)

This self-contained book is designed to be the only manual any reader will need to learn the skills necessary to read manufacturing blueprints. Beginning with the basics of blueprint reading, the book presents each topic in a clear, straightforward manner so that no prior knowledge is necessary in order to understand the subject. The charts, tables, and glossary of terminology provided are all the source material a reader needs to successfully complete the course work. Chapter 13, which deals with Geometric Tolerances and Chapter 14, which deals with Location Tolerances, are completely rewritten to reflect the current ASME Y-14.5M-1994 Standard on Geometric Dimensioning and Tolerancing. Unit 11, dealing with Metric Dimensions, has been updated, reflecting ISO requirements as well as the correct metric specifications dealing with dimensions and tolerances. Each new aspect of print reading is first introduced and fully explained before it is presented on prints. Machine trade field.

This book enables a reader with little or no previous experience to read, interpret, and use blueprints appropriate to machine tool processes. It begins with an introduction to the basic aspects of blueprint reading, including lines, abbreviations, and the language of blueprints. Each chapter builds to cover increasingly complex concepts. However, there is a thorough introduction to each new concept before it is applied to prints and real-world situations. Mathematics is developed gradually and in the context of blueprints so that readers will see the relationship between math and the manufacturing and inspection processes. The book takes a learn-by-doing approach, with numerous exercises that allow the reader to apply knowledge each step of the way.

Some key features of this new edition include:

• Unit 1 contains a valuable dictionary of terms, standard abbreviations, and alphabet of lines that form the foundation for further study.
• Unit 11 on metric dimensions has been updated to reflect the correct metric specifications dealing with dimensions and tolerances according to ISO standards.
• Units 13 and 14 on geometric tolerancing and location tolerances have been completely updated and rewritten to reflect the current ASME Y-14. SM-1994 Standard. New exercises have been added to help readers apply this to realistic prints.
