XXL-Milling Tool with innovative CFRP-structure.

This article describes the current status in the development of a very large milling tool with a diameter of more than 2,5 m which will consist of a newly investigated CFRP-structure. The material properties as well as light weight design permit a significant mass reduction compared to similar metallike tools. However, stiffness and damping characteristics have to maintain stable process conditions. Here, the structural layout, simulation results and model tests are presented. The  developments are subject of a research project which is sponsored by the Federal Ministry of Education and Research (BMBF). Within this project the companies FOOKE and INVENT cooperate with the Institute of Production Engineering and Machine Tools (IFW) at the Leibniz University of Hannover and the European Center of Adaptive Systems (ECAS).
