This method allows characterizing machine tool geometric errors depending on the kinematic of the machine and the work space available during the measurement time. The kinematic of the machine toll is affected by their geometric errors, which are different depending on the number and type of movement axes. The relationship between the various geometrical errors is different from relationship obtained in machine tool whit only lineal axes. Therefore, the identification strategy should be different. In the same way, the kinematic chain of the machine tool determines determines the position of the laser tracker and available space for data capture. This paper presents the kinematic model of several machine tools with different kinematic chains use to improve the machine tool accuracy of each one by volumetric verification. Likewise, the paper thus presents a study of: the adequacy of different nonlinear optimization strategies depending on the type of axis and the usable space available. info:eu-repo/grantAgreement/ES/MINECO/INNPACTO-IPT-2011-1191-020000 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-2521-2611 Samper Carnicer, David (orcid)0000-0001-7316-0003 Santolaria Mazo, Jorge Universidad de Zaragoza (orcid)0000-0002-8609-1358 Aguilar Martin, Juan José Universidad de Zaragoza 5002 515 Universidad de Zaragoza Departamento de Ingeniería de Diseño y Fabricación Ingeniería de los Procesos de Fabricación 615 (2014), 22-31 Key eng. mater.
