The circular test, which has commonly been carried out for measuring geometric error of NC ma-chine tool was introduced. Measuring Principles used in different devices for the test was analyzed, in which the advantages of grid encoder was highlighted. By using measuring system grid encoder KGM181 in verti-cal machining centre, the circular locus under different radius and different feed speed was measured and the data was dealt with by MATLAB software to analyze the relations of radius, feed velocity, and reversal spikes, The machining accuracy of the highest feed speed and trajectory radius range was obtained,which may promote the research of the calibration of NC machine.
