A relative displacement between cutter and workpiece formed by Incremental linear
superposition, which is created by all joints of the whole structure system of high-speed NC milling
machine, influences the machining precision. In this study, connection relations of major components in
machine tool are analyzed. The corresponding minimum displacement of vibration mode between the
principal axis and workpiece in low order mode of the whole machine is adopted as the evaluation indicator
of dynamic performance advantages and disadvantages. The comprehensive analysis is conducted on
natural frequency and vibration mode of machine tool through the assembly of modal force matrix, so as to
search out the corresponding maximum modal frequency and weak structural links, to correct modal
frequencies of main structural components for separation, to avoid substantial increase of the whole
vibration amplitude caused by the fact that the driving frequency of the whole machine is close to the
modal frequency of component and to achieve the goal of optimizing the whole structure. Compared with
the whole finite element, the analytical accuracy error of this method is less than 2.5% and the analysis
time can be reduced by 50%.
