The goal of the research project ArenA-FOi (Application-oriented analysis of resource-saving and energy-efficient design of industrial facilities for the optical industry) is to create a new processing machine for manufacturing high precision optics. The primary kinematic system of the new machine is a Hexapod, which stands for high precision positioning and repeated accuracy. In addition, a Hexapod system is characterized by high stiffness and the reduction of mass, compared to existing machines. In the first phase of the project, the focus is on the machine concept, based on the required product range. Furthermore, it should be possible to create spiral and raster tool-paths for the process of machining. Especially, the raster tool-path is only applicable by a high radius of curvature which is limited by the maximum inclination of the Hexapod. If the result of the machine concept shows that an additional axis is needed, this axis must ensure synchronous control. Up to now, the processing of aspherical lenses is carried out by using the dwell time and vertical machining for the spherical best fit geometry. In this research project, we want to machine surface normal at every single point of the entries process and we also expect a quality improvement. In this paper, only the project concept and the project's first phase — the plant construction and the development of aspherical surfaces — are discussed. |
