Coordinate measuring machines (CMMs) are commonly used to determine the parameters of a circular feature using different criteria like minimum zone, least squares, minimum circumscribed or maximum inscribed. For many years, thermal effects have been the largest single source of dimensional errors and equipment non-repeatability. Thermal error variation has a complex nonlinear nature which makes it difficult to handle. Theoretical analysis and analytical representation of almost components of the CMMs measuring uncertainty at the beginning of measurement makes possibilities to create measuring errors models in every CMMs knots, considering temperature influences and estimate there. This work presents the equations for the components of the volumetric error of a Coordinate Measuring Machine including temperature influences and the interest to the temperature effects influence determination on the CMMs uncertainty and there estimation with help of the mathematical statistics methods, for example correlation theory, factorial design and ANOVA.
