Universidad de Zaragoza Adequacy of technical and commercial alternatives applied to machine tool verification using laser tracker 2016 Access copy available to the general public Unrestricted Besides presenting a volumetric verification technique that allows characterization of the different geometric errors of a machine tool (MT) depending on its kinematic chain and geometry through a kinematic model, this paper investigates the influence of measurement tools and techniques available on the final accuracy of the MT. Volumetric verification based on a laser tracker (LT) relates the coordinates of the tool with the coordinates of the LT, including it into the kinematic model. Using a non-lineal optimization process, approximation functions that characterize the joint influence of MT geometric errors are obtained. However, measurement data will be affected by previous compensation of the MT, the accuracy of the measurement system, LT measurement technology, the type of retroreflector used, and techniques used to improve data accuracy, among other sources of errors. This paper studies the adequacy of different commercial alternatives such as: retroreflectors, LTs from different manufacturers, etc., that can be applied in MT verification using a long-range MT. As the accuracy is strongly affected by the uncertainty of its angular encoders, the multilateration technique tries to improve data accuracy using only LT radial information. Nonetheless, a new bundle adjustment which uses radial and angular information is presented in current metrology software. This paper studies both techniques and analyzes their adequacy for MT verification too. info:eu-repo/grantAgreement/ES/DGA/T62 info:eu-repo/grantAgreement/ES/MINECO/DPI2013-46979-C2-1-P info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 0.109 2016 Applied Mathematics 2016 Q4 Computer Science Applications 2016 Q4 Engineering (miscellaneous) 2016 Q4 Process Chemistry and Technology 2016 Q4 Instrumentation 2016 Q4 Materials Science (miscellaneous) 2016 Q4 Fluid Flow and Transfer Processes 2016 Q4 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0001-7316-0003 Santolaria, J.
