Trades & Technology

For introductory Blueprint Reading courses geared to students in the manufacturing trades, such as Machine Operators, General Machinists, and Tool and Die Machinists.

Being able to read and correctly interpret a blueprint is a necessary skill in the industrial world today. Designed in a workbook format, this manual begins with the basics of blueprint reading and progresses to visualization and then to multi-view drawings. Assuming no prior knowledge of the subject, it includes charts, tables, a glossary of terms, and a mathematics appendix to help students comprehend material. This edition features expanded coverage of GDT, more information on profile tolerances and drawings produced in CAD. Designed for those in a manufacturing trade, this is a straightforward resource that helps prepare students to enter the industrial field of work.

"Larry" Smith is currently employed as a professor at St. Clair College in Windsor, Ontario for the last 28 years and is also a ToolMaker Leader at the Ford Motor Company, Experimental Glass Division in Lincoln Park, MI for 11 years.  He is a member of the Technical Committee on Technical Drawings and Symbols (B159) of Canadian Standards Association.

Professor Smith has earned a Masters of Arts Degree in Education from Central Michigan University in Mt. Pleasant, MI and a Bachelor of Arts in Histoyr and English from Lawrence Technical University in Detroit, MI.  He also holds an Associates in Science Degree and many certificates including Senior Level Certification for Geometric Dimensioning and Tolerancing from the American Society of Mechanical Engineers.

The revised sixth edition of this classic blueprint reading text provides students and professional machinists with the background needed to understand blueprints and quality standards. This book combines principles with real-world exercises using authentic plans. Simple blueprints are introduced, and then new features are added to them to create increasingly complex drawings as the reader’s understanding grows.

Key features include:

• Updated text and illustrations reflecting the latest practices
• Additional drawings with SI measurements
• Blueprints recreated using Computer-Sided Design (CAD)
• Current standards from the American Society of Mechanical Engineers (ASME)
