面向任务的测量不确定度评估原理和方法

Principle and Method of Evaluating Task-specific Measurement Uncertainty for CMM

坐标测量机是典型的面向任务的测量设备,测量任务的改变将引入不同的测量不确定度。怎样评估坐标机面向任务的测量不确定度,目前我国还没有这方面专门的技术规范。参考ISO/TS15530系列标准,介绍了坐标测量机面向任务的不确定度评估原理和方法。

Coordinate measuring machine（CMM） is a typical task-specific measurement instrument.Different uncertainty will be led when measured object has been changed.At present,there is no corresponding standard and specification for evaluating task-specific measurement uncertainty for CMM in our country.Basde on ISO/TS15530 series standard,the principle and method of evaluating task-specific measurement uncertainty was presented in this paper.
