During the conduct of the National Science Foundation sponsored American Society of Mechanical Engineers Workshop on Mechanical Tolerancing (September 28 - October 2, 1988), it became evident that there was a need to determine the shortcomings and ambiguities of inspection systems that assess deviations of part geometries according to current standards and practices of dimensioning and tolerancing. A study will be conducted to examine the difference between the results of current sample measurement systems measuring workpieces dimensioned and toleranced to current geometric dimensioning and tolerancing (GD&T) standards. The ambiguities found can be traced to the need for a mathematical foundation for current standards. The final report will consist of a draft standard to be supplied to the National Science Foundation and the American Society of Mechanical Engineers Y14 Committee for approval as the American National Standard.

在美国国家科学基金会主办的美国机械工程师学会机械公差研讨会（1988 年 9 月 28 日至 10 月 2 日）期间，很明显需要确定根据当前尺寸和公差标准和实践评估零件几何形状偏差的检查系统的缺点和模糊性。 将进行一项研究，以检查当前样品测量系统测量工件尺寸和公差是否符合当前几何尺寸和公差（GD＆T）标准的结果之间的差异。所发现的含糊之处可以追溯到当前标准对数学基础的需求。最终报告将包括一份标准草案，将提交给美国国家科学基金会和美国机械工程师学会 Y14 委员会批准为美国国家标准。
