This paper is dealt with about the cause of generating of vibration of a machining center. The machining center consists of the head, the column, the saddle, and the bed. The vibrational experiment at the cutting of the machining center was conducted. The cutting conditions are feed rates and depths of cut. The two vibration modes are measured from the results of the experiment each other independently. One is a pendulum vibration mode. Another is a parallel motion mode of the head. Eigenvalue analysis of the substructure system which consisted of the head, the column, and the saddle was calculated by Finite Element Method (FEM). Two vibration modes are agreed with the results of the experiments. The causes of generating of these vibration modes by the feed rate and the depths of cut are considered by cutting theory.
