ASME-Y14.5 – 2009 Edition – One of our top-selling engineering standards

ASME-Y14.5 – 2009, Geometric Dimensioning and Tolerancing, is one of Document Center Inc.’s all-time top selling engineering standards.  It is the basic document for stating and interpreting geometric dimensioning and tolerancing requirements for use on engineering drawings and in related documents.

The history of the Y14 series on engineering drawings goes back to 1915, some 35 years after the ASME organization was founded.   It’s roots come from the need of automobile manufacturers and other industrial facilities to standardize engineering drawings and terminology among their suppliers.  The ASME-Y14.5 (also known as ASME-Y14.5M, from it’s now obsolete 1982 metric edition) is the centerpiece of this well-used series.

Important changes in the new ASME Y14.5 – 2009 include datum references and degrees of freedom, composite position tolerances, surface boundaries and axis methods of interpretation, profile tolerances, and symbology and modifiers tools.
