Abstract

Many CNC machine tools are used in general-purpose machining environments, resulting in a wide variety of machining conditions being present at the cutting tool. The requirement for guide-way to bearing clearances and limited mass of the structural elements results in a limited stiffness between the cutter and workpiece. This, coupled with the inertial effect of the structural element masses and drive-system, can lead to complex vibration modes that are affected by the axis positions and machine tool configuration. Therefore, the study of the dynamic behaviour of the machme is important in determining the response of the machine's structure to an external force. In this paper, the results and the setup of an experimental modal analysis performed on a vertical milling
