GD&T is a universal design language that has been rigorously studied and applied by thousands of manufacturers around the world. It is widely considered by mechanical engineers to be an essential tool for communicating design intent — that parts from technical drawings have the desired form, fit, function and interchangeability.
ASME Y14.5-2009 includes important changes addressing the concept of feature design, datum references and degrees of freedom, surface boundaries and axis methods of interpretation, profile tolerances and symbology and modifiers tools. The updated standard has also been fine-tuned with ease of use and readability in mind, including separate sections dedicated to profile, orientation and form.
ASME Y14.5-2009 is available for immediate purchase for $169 USD on the ASME website. In addition, ASME offers related GD&T standards, personnel certification, handbooks and training courses to aid engineers in understanding the language of GD&T. Beginning April 27, four training courses will be available throughout the year, ranging from basics of GD&T to drawing interpretation. In addition, discounts on all these related GD&T offerings are available through August 31, 2009.
“By providing uniformity in drawing specifications and interpretation, geometric dimensioning and tolerancing reduces the guesswork throughout the manufacturing process, therefore improving quality, lowering costs, and shortening deliveries,” said ASME President Thomas M. Barlow.
The release of this revised standard coincides with ASME’s celebrating the 125th-year anniversary of its codes and standards development, and illustrates this unique contribution to worldwide knowledge and technology transfer. For more information on ASME Y14.5-2009, visit: http://go.asme.org/gdt.
ASME helps the global engineering community develop solutions to real world challenges. Founded in 1880 as the American Society of Mechanical Engineers, ASME is a not-for-profit professional organization that enables collaboration, knowledge sharing and skill development across all engineering disciplines, while promoting the vital role of the engineer in society. ASME codes and standards, publications, conferences, continuing education and professional development programs provide a foundation for advancing technical knowledge and a safer world.
