The main aim of machine tool verification is to reduce the influence of quasi-static errors, especially geometric errors. As these errors show systematic behavior, their influence can be compensated. However, verification itself is influenced by random uncertainty sources that are usually not considered but affect the results. Within these uncertainty sources, laser tracker measurement noise is a random error that should not be ignored and can be reduced through adequate location of the equipment. This paper presents an algorithm able to analyse the influence of laser tracker location based on nonlinear optimisation, taking into consideration its specifications and machine tool characteristics. The developed algorithm uses the Monte Carlo method to provide a zone around the machine tool where the measurement system should be located in order to improve verification results. To achieve this aim, different parameters were defined, such as the number of tests carried out, and the number and distribution of points, and their influence on the error due to the laser tracker location analysed. info:eu-repo/grantAgreement/ES/DGA/T56-17R info:eu-repo/grantAgreement/ES/MINECO/DPI2017-90106-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.623 2020 METALLURGY & METALLURGICAL ENGINEERING 17 / 80 = 0.213 2020 Q1 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 152 / 333 = 0.456 2020 Q2 T2 PHYSICS, CONDENSED MATTER 27 / 69 = 0.391 2020 Q2 T2 PHYSICS, APPLIED 51 / 160 = 0.319 2020 Q2 T1 CHEMISTRY, PHYSICAL 79 / 162 = 0.488 2020 Q2 T2 0.682 2020 Materials Science (miscellaneous) 2020 Q2 Condensed Matter Physics 2020 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Pérez, Pablo (orcid)0000-0002-1093-8233 Albajez, José Antonio Universidad de Zaragoza (orcid)0000-0003-4839-0610 Santolaria, Jorge Universidad de Zaragoza (orcid)0000-0001-7316-0003 Velázquez, Jesús Universidad de Zaragoza (orcid)0000-0001-9617-1004 5002 515 Universidad de Zaragoza Dpto.
