The ASME Y14.5-2009 Standard on Dimensioning and Tolerancing

The new ASME Y14.5 (2009) dimensioning and tolerancing standard was published in April, 2009. According to the American Society of Mechanical Engineers (ASME), "a consensus committee of experts revised Y14.5 for 21st-century applications." The new standard is a replacement of ASME Y14.5M-1994.

The revised standard includes changes to:

• The concept of feature of size
• Datum references and degrees of freedom
• Composite position tolerances
• Surface boundaries and axis methods of interpretation
• Profile tolerances
• Symbology and modifiers tools 

As the foremost expert on GD&T, ETI president Alex Krulikowski was involved in creating this new version of ASME Y14.5. He has developed several products to help with the transition from the 1994 to 2009 standard:

Fundamentals of Geometric Dimensioning and Tolerancing, Using Critical Thinking Skills by Alex Krulikowski
The Fundamentals of Geometric Dimensioning and Tolerancing Using Critical Thinking Skills textbook has been completely updated to reflect the changes in the ASME Y14.5-2009 Standard. This third edition preserves the best features of the first two editions while adding new material that reflects the changes in the field of geometric tolerancing.

Our new full-color textbook contains more than 400 pages with several new features that aid in the the understanding of geometric tolerancing. It also focuses on critical thinking skills that help the reader when applying newly learned GD&T concepts on the job. It's the most practical and easy-to-use GD&T textbook on the market.

Each of the textbook's 27 chapter focuses on a major topics that must be mastered to be fluent in the fundamentals of geometric tolerancing. Each goal is defined and supported by a set of performance objectives. There are more than 260 performance objectives that describe specific, observable, measurable actions that the student must accomplish to demonstrate mastery of each goal and are a key to success for both the student and the instructor.

Material that builds and develops critical thinking skills is contained within each topic, with questions that utilize those skills at the end of each chapter.
