Coordinate measuring machines (CMM) are main instruments of measurement in laboratories and in industrial quality control. A compensation error model has been formulated (Part I). It integrates error and uncertainty in the feature measurement model. Experimental implementation for the verification of this model is carried out based on the direct testing on a moving bridge CMM. The regression results by axis are quantified and compared to CMM indication with respect to the assigned values of the measurand. Next, testing of selected measurements of length, flatness, dihedral angle, and roundness features are accomplished. The measurement of calibrated gauge blocks for length or angle, flatness verification of the CMM granite table and roundness of a precision glass hemisphere are presented under a setup of repeatability conditions. The results are analysed and compared with alternative methods of estimation. The overall performance of the model is endorsed through experimental verification, as well as the practical use and the model capability to contribute in the improvement of current standard CMM measuring capabilities.
坐标测量机（CMM）是实验室和工业质量控制中的主要测量仪器。已制定了一个补偿误差模型（第一部分）。它将特征测量模型中的误差和不确定性进行了整合。基于对移动桥式坐标测量机的直接测试，对该模型进行了验证的实验实施。按轴的回归结果进行了量化，并与坐标测量机相对于被测量指定值的指示进行了比较。接下来，完成了对长度、平面度、二面角和圆度特征的选定测量测试。在重复性条件设置下，给出了长度或角度校准量块的测量、坐标测量机花岗岩工作台的平面度验证以及精密玻璃半球的圆度测量。对结果进行了分析，并与替代估计方法进行了比较。通过实验验证以及实际应用和该模型对提高当前标准坐标测量机测量能力的贡献能力，认可了该模型的整体性能。
