研究了坐标测量机(CMM)形状测量任务的不确定度评定问题,实现了CMM形状测量的不确定度快速、可靠地评定。给出了测量不确定度评定与表示指南(GUM)和蒙特卡洛随机抽样两种不确定度合成方法,平面度测量实验验证了不确定度评定方法的可行性,实验结果表明:GUM确定的不确定度精度意义不可靠,扩展不确定度相对于实际情况扩大了11.1%; 解决CMM形状测量任务的不确定度评定问题,具有较强的典型性和代表性,可有效地应用于解决其他精密仪器的不确定度评定问题。
Abstract
The coordinate measuring machine (CMM) uncertainty for evaluating the form errors-oriented measurement tasks has been systematically studied, thus the rapid and reliable evaluation of the CMM measurement uncertainty can be realized.Two uncertainty combined methods based on Guide to the Expression of Uncertainty in Measurement (GUM) and Monte Carlo method are provided.The feasibility of the evaluation method has been verified by measurement example of flatness.The experimental result shows that precision significance of uncertainty determined by GUM is unreliable, the expanded uncertainty increased by 11.1% compared with actual situation.To systematically solve the problem of the CMM uncertainty for evaluating the measurement tasks targeting form errors is typical and representative, which can be effectively applied to solve the uncertainty evaluation problems of other precision instruments.
