Geometric Dimensioning and Tolerancing

The current revision of this book based on ASME Y14.5-2009 is a great reference book. The chapters of the book follow the revised format of Y14.5-2009 instructing on general dimensioning, tolerancing, and related principles first; followed by symbology and datums. It then discusses the geometric tolerances in the order in which they should be considered for use. It has a lot of examples, great questions and many helpful indications of what is new in the 2009 standard. Many people don't understand or use GD & T properly. This book helps by showing the proper methods to apply GD & T. I wish a book like this was available when I started to learn GD & T many years ago. It would have made it easier. I teach GD & T at my company and I reccomend this book to my students to keep as a guide and to use for reference. I personally use two books for referencing GD & T. This book and the actual ASME tansdard. They are the only two I need.

This text/workbook provides excellent training on the basics of GD & T. The book is easy to read and uses extensive examples. The content makes the ASME standard understandable. The chapters are organized in a logical sequence. The first two chapters provide a very important overview of dimensioning, tolerancing, and an introduction to GD & T symbology. This helps lead you into learning GD & T concepts gradually and solidly as basic elements build toward more complex technology. The book provides a review test after each chapter and a comprehensive final test covering all concepts. Each chapter also has projects for the drafting students and print reading exercises for the manufacturing students. Additional tests, and projects are found in the Instructor's Guide along with sample course syllabi. Use this book if you want a text that clearly and easily teaches you the GD & T basics.

I am a college instructor, and have taught classes using this text. It is an excellent choice for use in a classroom setting. The chapters are laid out in a logical order so the student progresses through the concepts in a meaningful manner that leads to thorough understanding of the standard. The diagrams and examples are well designed and explained. The chapter exercises, tests, and drawing problems are useful to the instructor and educational for the students.In addition to being a classroom text, it is a very good reference book for the work place. It will be useful to anyone in the engineering, drafting, inspection, programming and machining departments. The engineer and draftsperson will use this book as a reference to develop drawings that adhere to the ANSI and ASME GD & T standards, and it will assist others in the interpretation of the drawings.I recommend this book to anyone who is taking a GD & T class or wants to teach themselves this very useful standard.
