Abstract
A method for compensating measurement errors caused by the deformation of a component defining a slide axis in a measurement machine, comprising the steps of calculating the curvature of the component as a function of the difference between the current temperature Tc and a reference temperature Tr at which the geometric compensation map of the machine has been obtained, calculating correction values for the compensation parameters stored in the compensation map as a function of the curvature, and updating the compensation map with these correction values.
