RT Journal Article SR Electronic A1 Čep, Robert A1 Malotová, Šárka A1 Vrba, Vladimír T1 Comparison of the Measuring Devices during the Evaluating of Circularity Deviation JF Acta Mechanica Slovaca YR 2017 VO 21 IS 3 SP 12 OP 16 DO 10.21496/ams.2017.021 UL https://www.actamechanica.sk/artkey/ams-201703-0003.php AB The contribution deals with the comparison of devices for measuring and evaluation of circularity of deviation. The circularity of deviation was measure on the specific component using in practice. The deviation was measured with using standard circular gauge Formtester MMQ 44 CNC and 3D measuring device SCAN Max. The results were statistical evaluated in tables. Part of the results is the technical and economic evaluation too.
