Based on the basic theory of multi-body system, the description method of complex mechanical system is introduced. The topology of multi-body system, the low-order body array and the construction method of transformation matrix are expounded. The basic law of geometric error modeling of NC machine tools is studied. Taking the five-axis machining center as an example, the geometric error modeling process is elaborated and the concrete mathematical expressions are given.
