“…Each such machine is tested and checked before it arrives at the customer's. Both contact and noncontact methods are used in tests [1][2][3][4][5][6][7][8][9][10]. Frequently, some of the measured errors need specialist testing methods, and in general, these are non-contact interferometric methods.…”

“…The fundamental limitation of the stationary interferometric methods in the machine measurements is the considerable time amount needed to set the interferometer's optics, especially for the machines of a tooling range over a few meters. The possibility of measuring the whole tooling axis and obtaining error information at the full range motion [1][2][3][4][5] constitutes an undisputable advantage. The second group of diagnostic tools are the tools based on contact measurements.…”

This paper presents the evaluation of the influence of the feedmotion speed on the value of selected geometric errors of CNC lathe CTX 310 eco by DMG, indentified by QC 20 Ballbar system. Diagnostically evaluated were: the deviation of the axis squareness, reversal spike, and backlash. These errors determine the forming of the dimensional and shape accuracy of a machine tool. The article discusses the process of the CNC diagnostic test, the diagnostic evaluation and formulates guidelines on further CNC operation. The results of measurements were presented in tables and diagrams.
