The proposed algorithm of form deviation evaluation is based on the interpolation process of corrected measured points. Corrected measured points are the results of probe radius correction process applied in the coordinate measuring technique. The interpolation is conducted by using of the Lagrange and Chebyshev methods. The developed algorithm of deviation calculation can be implemented in most commercial software cooperating with a coordinate measuring machine. In the article the results of numerical and experimental investigations connected with the proposed algorithm are presented. The numerical investigations concern the simulation of contact coordinate measurements of products, which can be conducted on a coordinate measuring machine. The measured products are composed of free-form surfaces characterized by various curvature and consequently various degree of geometric complexity. The experimental investigations were conducted in order to verify the results of simulation studies. The presented method improves the accuracy of measurements of free-form surfaces of products"},{"@xml:lang":"sl","#text":"Glavni cilj predstavljene raziskave je bil razvoj nove metode za izračunavanje odstopanja oblik, ki bo uporabna pri koordinatnih meritvah površin izdelkov poljubnih oblik. Nova metoda mora biti primerna tudi za programsko opremo koordinatnih merilnih strojev. Predlagani algoritem za vrednotenje odstopanja oblik bazira na metodi interpolacije korigiranih merilnih točk po Lagrangeu in Čebišovu. Algoritem razdeli točke, ki jih izmeri koordinatni merilni stroj, v skupine po pet točk. Skupine se interpolirajo po obeh omenjenih metodah interpolacije in pri tem se oblikujejo skupine polinomskih krivulj četrtega reda, ki predstavljajo dejansko obliko merjenca"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-G04FEQCL","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-G04FEQCL"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-G04FEQCL/752be12e-46c8-4733-a59d-790974b48925/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-G04FEQCL/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-G04FEQCL"}}}}
