| 要旨 | This paper presents the kinematic parameter optimization for stiffness improvement of parallel mechanism-based machine tools. The relation between the stiffness of the spindle end and pose variation is analyzed using the force balancing model of the parallel mechanism. Then, both the relation between stiffness and machine vibration and the relation between stiffness and kinematic parameters are examined. By designing with the virtual machine simulator, kinematic parameter optimization is performed without any link coregion problems. It provides not only high stiffness, but also reduction of machine vibration and machined surface undulation. This kinematic parameter optimization is applied to the parallel mechanism-based milling machine HexaM, and the validity is verified by simulations and experiments. |
