For a long time, the evaluation of measurement uncertainty in coordinate measuring machines (CMMs) has been one of the most prominent research areas in the field of dimensional metrology. This is because coordinate measuring machines, whether equipped with contact or non-contact sensors, are dominant in assessing the conformity of workpieces with specifications. They are characterized primarily by a high degree of flexibility and accuracy, but they are also complex metrological systems with numerous sources contributing to measurement errors, i.e., measurement uncertainty. Numerous methods and approaches have been developed so far for the evaluation of CMM measurement uncertainty, and it is generally accepted that this is a highly challenging and complex task. Experimental methods, simulation-based methods, analytical approaches, as well as the ISO 15530 series of standards have proposed their own methodologies. The aim of this paper is to present the current state of research in this field. The authors of this paper have many years of experience in this area, and several case studies will be presented
