Expedited Award for Novel Research: Enhance the Developmentof the National Standard for the Performance of Coordinate Measuring Machines and Measuring Machine Software

三坐标测量机（cmm）是目前用于制造零件尺寸质量控制的主要测量仪器。为了确保这些机器的精度足以满足预期用途，需要制定性能标准。作者将与批准该标准的美国机械工程师协会（ASME） B89.1.12委员会密切合作，编写一个新的更新版本的美国国家标准的cmm性能。新标准将消除前一版本（1985年）中确定的歧义，改进关于球棒测量的部分，并增加对旋转轴、大型机器和“触火”探头的处理。该标准的完整版本将于1989年9月提交给委员会。

Coordinate Measuring Machines (CMMs) are now the principle measuring instrument used for quality control of the dimensions of manufactured parts. In order to ensure that the accuracy of these machines is sufficient for the intended use, performance standards are required. The author will write a new updated version of the American National Standard for the performance of CMMs in close cooperation with the American Society of Mechanical Engineers (ASME) B89.1.12 committee who approves this standard. The new standard will remove ambiguities identified in the previous version (1985), improve the section on ball bar measurement, and add treatments for rotary axes, large machines and "touch-fire" probes. A completed version of this standard will be delivered to the committee in September of 1989.
