Title
High precision milling with a novel compliant machine tool
Abstract
For precision milling manufacturing machine tools with high stiffness K and high masses m are state of the art. Usually this will be achieved due to heavy and large machine beds and frames. Hence, a new approach based on the compensation of the dynamic dislocation was investigated. The aim of this new approach was to develop a high dynamic machine tool with a compliant machine frame. Therefore, a novel compliant three- Axes machine tool for high precision milling based on an Ethercat Technology® and the open source ethercat master etherlab machine is developed by the Technische Universität Berlin and the Fraunhofer Institute for Production Systems and Design Technology. For the dynamic dislocation a Kalman-filter is integrated in the machine control which calculates the tool body with respect to the tool-center-point TCP and its velocity v. For the verification milling structures are manufactured with the compliant machine tool.
