Many of these systems are directly mounted in the machine spindle, so the measuring uncertainty is affected by clamping positioning and orientation variations, especially when integrating optical systems based on machine vision. This paper presents a self-calibration technique for vision systems by using redundant information of on machine measurements, avoiding extra mechanical anchoring or calibration means. It has been applied to a vision system with the angular placement uncertainty of a tool holder coupling being the main uncertainty contributor. A milling machine pilot case has been selected for demonstration, showing an effective self-calibration capability both in laboratory and industrial conditions. 000075435 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000075435 590__ $$a2.791$$b2018 000075435 591__ $$aENGINEERING, MULTIDISCIPLINARY$$b23 / 88 = 0.261$$c2018$$dQ2$$eT1 000075435 591__ $$aINSTRUMENTS & INSTRUMENTATION$$b17 / 61 = 0.279$$c2018$$dQ2$$eT1 000075435 592__ $$a0.724$$b2018 000075435 593__ $$aApplied Mathematics$$c2018$$dQ1 000075435 593__ $$aCondensed Matter Physics$$c2018$$dQ1 000075435 593__ $$aStatistics and Probability$$c2018$$dQ1 000075435 593__ $$aElectrical and Electronic Engineering$$c2018$$dQ1 000075435 593__ $$aInstrumentation$$c2018$$dQ1 000075435 593__ $$aEducation$$c2018$$dQ1 000075435 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000075435 700__ $$aLeizea, I. 000075435 700__ $$0(orcid)0000-0001-7152-4117$$aYagüe-Fabra, J.A.$$uUniversidad de Zaragoza 000075435 700__ $$aZatarain, M. 000075435 7102_ $$15002$$2515$$aUniversidad de Zaragoza$$bDpto.
