We made a real effort to address difficult topics such as profile reporting, MMC and bonus tolerance, surface interpretation, patterns, composite FCF's, and optimization. Extracting numerical measurement data from these GD&T characteristics has proven to be a very different challenge. This standard is necessary because the well-known ASME Y14.5 standard for Dimensioning and Tolerancing only defines conformance in terms of pass/fail requirements - tolerance zones and acceptance boundaries. The primary objective of Y14.45 is to provide standardized definitions and formats for reporting GD&T measurement data. I am very pleased to announce that the long-awaited ASME Y14.45 standard for Measurement Data Reporting has finally been published!
