Science and Education Publishing American Journal of Mechanical Engineering 1 7 2013 11 17 Comparison of the Cylindricity Deviation Using Different Evaluation Methods 339 342 EN Miroslav Dovica Technical University, Mechanical Engineering Faculty, Department of Biomedical Engineering and Measurement, Košice, Slovakia Alexander Végh AJME20131737 10.12691/ajme-1-7-37 2013 10 06 2013 10 16 2013 11 17 This paper deals with the measurement and the evaluation of cylindricity deviation of the rotational symmetrical workpiece. Coordinate Measuring Machine (CMM) with X-Ray tomography was used for the measurement. For the evaluation of the cylindricity deviation, we applied standard Gaussian cylinder. Data obtained by the measurement is compared using the VG Studio and Calypso software. At the end of this paper, the experimental data is presented.
