The 2018 Ultimate GD&T Pocket Guide explains the most common rules, symbols, and concepts used in geometric dimensioning and tolerancing. This valuable on-the-job resource clarifies how to interpret standard-compliant technical drawings that use the ASME Y14.5-2018 Standard. The guide’s 128 information-packed pages contain more than 100 detailed examples and numerous topical reference charts, including a conversion chart illustrating X and Y coordinate measurements to a diameter deviation.
The pocket guide includes full definitions of major concepts with explanations of each symbol and modifier. It provides application examples that will help you envision concepts — including examples of how to apply datums. You’ll find sections on surface texture and composite tolerancing, clarification of important rules and topics, and examples of fixed and floating fastener assembly position tolerance calculations. The guide also includes English and metric rulers, orthographic view projection systems, references to the 2018 Standard that allow you to find more about a topic, plus caution statements that warn you of common pitfalls in the use of tolerancing concepts.
The 2018 pocket guide is packed with information and easy to use. The spiral binding allows it to lie flat, and index tabs provide quick access to topics. A topical index in the fold-out front cover makes finding content easy, and a geometric tolerancing summary chart in the back cover gives quick access to symbol application. There’s a glossary of terms and a handy inch/millimeter conversion chart. Cross-references to other pages within the pocket guide that contain application examples or other related information are also included. The Ultimate GD&T Pocket Guide is an economical reference tool you can’t afford to be without. It’s the perfect on-the-job reference for your geometric dimensioning and tolerancing needs.
