【Abstract】 This paper introduces the principle and results of determining dynamic compliance matrix of a knee-and-column milling machine at working point through stAnulus-rcsponsc test by means of exciting relatively between tool andworkpiece, as well as result8 of a modal analysis. The confidence of these results is shown by comparing them with the results of cutting tests. The necessity of modeling machine tool structurc with a dynamic equivalent system with multi masses and multi degree of freedom is poited out.更多还原
