Analysis of DMU40 CNC machine center - Part I: Overview

Abstract

This note is the first part of an extended research-analysis work, where our aim is to summarize the concepts of the methods and measurements, which we will present in the later articles. The research is focusing on the dynamic behavior of the DMU 40 5-axis CNC machine center, which can be found in the workshop of the Department of Machine Tools. This means that we would like to determine the magnitude of the dynamic stiffness of the machine tool, by calculating the value of the natural frequencies by final element method (analytically, and with software), and with the help of an experimental test.
