Universidad de Zaragoza Modelling, kinematic parameter identification and sensitivity analysis of a Laser Tracker having the beam source in the rotating head 2016 Access copy available to the general public Unrestricted This paper presents a new kinematic model, a parameter identification procedure and a sensitivity analysis of a laser tracker having the beam source in the rotating head. This model obtains the kinematic parameters by the coordinate transformation between successive reference systems following the Denavit–Hartenberg method. One of the disadvantages of laser tracker systems is that the end-user cannot know when the laser tracker is working in a suitable way or when it needs an error correction. The ASME B89.4.19 Standard provides some ranging tests to evaluate the laser tracker performance but these tests take a lot of time and require specialized equipment. Another problem is that the end-user cannot apply the manufacturer’s model because he cannot measure physical errors. In this paper, first the laser tracker kinematic model has been developed and validated with a generator of synthetic measurements using different meshes with synthetic reflector coordinates and known error parameters. Second, the laser tracker has been calibrated with experimental data using the measurements obtained by a coordinate measuring machine as nominal values for different strategies, increasing considerably the laser tracker accuracy. Finally, a sensitivity analysis of the length measurement system tests is presented to recommend the more suitable positions to perform the calibration procedure. info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 2.359 2016 ENGINEERING, MULTIDISCIPLINARY 19 / 85 = 0.224 2016 Q1 T1 INSTRUMENTS & INSTRUMENTATION 15 / 58 = 0.259 2016 Q2 T1 0.726 2016 Education 2016 Q1 Instrumentation 2016 Q1 Electrical and Electronic Engineering 2016 Q1 Statistics and Probability 2016 Q2 Condensed Matter Physics 2016 Q2 Applied Mathematics 2016 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0001-7316-0003 Santolaria, J.
