Simulation Research On 5-Axis NC High-Speed Machining Center

Now, following the development of technology and the emergency of the new products, high speed, high efficiency, high precision and high rigidity have been the main developing trend of numeric-control (NC) machine tools. To meet the need of NC machine tools' development and adapt to the heated market competition, we must use advanced manufacturing technology to design the machine tool with excellent service capability. We are concerned about the structure and the principle of high-speed machines and how to work better to enhance the efficiency of high-speed machine. In this paper, the virtual designing and the virtual dynamics simulation of high-speed machining tool are done using virtual manufacturing technology on the basis of virtual production line.Firstly, the structure of HERMLE MACHINING CENTER C 40 is analyzed. The main modules are chosen. The Virtual models of the modules of HERMLE MACHINING CENTER C 40 are accomplished adopting parametric entity modeling technology based on feature. And then the virtual assembly models of components and whole machine are set up using virtual assembly technology. Using ANSYS software, the inherent frequencies and the librating models are gotten based on the mode analyzing technology. The virtual model of HERMLE MACHINING CENTER C 40 is proved to be suitable for use.
