Validation of Virtual CMM-Based Method for Uncertainty Estimation of Measurements Performed on Five-Axis Coordinate Measuring Machines

According to guidelines of international standards it is necessary that all methods used in calibration and test laboratories for determination of measurement result and uncertainty should be validated. It is important especially in case of methods that are newly developed to fit some purpose. One of such methods is a virtual CMM-based method that was designed for uncertainty estimation of measurements performed using five-axis coordinate measuring machines. Different methodologies were chosen for validation of this approach. Theoretical aspects of them like basic rules of their implementation and selection of validation criterions were presented in this paper along with description of validation experiments and their results. The main finding of this research is that Virtual CMM prepared for five-axis coordinate measuring machines passed the validation carried out using all mentioned methodologies.
