Abstract:This work presents the equations for the components of the volumetric error of a Coordinate Measuring Machine (CMM) considering thermal influences. These equations were applied to a moving bridge CMM and combines homogeneous transformations, regression techniques and least squares algorithm. The magnitudes of both the geometric errors and its thermally induced variations were collected by means of a Laser interferometric system, a mechanical square and an electronic level. Simultaneously, temperature values we… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
